Individual

Personal Characteristics

Age (AGE__)

(1982 to present)

• Definition: The age is calculated by subtracting the individual's year of birth from the tax year of the data. The age is defined as of December 31^st of the tax year.
• An individual’s age may not be consistent from one year to the next. It is recommended that age be recalculated from the year of birth (YOB) information on the current LAD register that contains the most recent age information available.
• Any taxfiler or imputed individual with an age greater than 99 does not have his or her actual age in the field, but the value 99.
• Derived from: Personal information section, T1 tax form (1982 to present)
• LAD: AGE__   I, P, K

Sex of individual (SXCO_)

(1982 to present)

• Definition: Each record is assigned a code to represent the gender of the taxfiler. The code is assigned by the Canada Revenue Agency by matching the social insurance number (SIN) reported on the tax return to the SINMASTER, a Human Resources and Social Development Canada (HRSDC) file. This file contains the gender of every person who has received a SIN. Imputed children are not assigned a sex code (their sex code is blank) while imputed spouses are given a sex code opposite to that of their filing spouse. Non-matched taxfilers who have no sex code are assigned one randomly. 
• Following are the possible codes:
  • ‘   ’ (blank) –  sex code not identified
  • ‘F’ –  denotes female
  • ‘M’ –  denotes male
• Due to the method of assigning a sex code, on rare occasions the sex of some individuals may change from year to year. For consistency, use the LAD Register for this variable.
• Derived from: Edit and Imputation
• LAD: SXCO_   I, K      character

Marital status (MSTCO)

(1982 to present)

• Definition: Marital status is a numeric code representing the marital status of the taxfiler.  
• The marital status and corresponding codes are: 
  • ‘   ’  –   (blank) Missing value
  • ‘M’ –   Married
  • ‘C’  –   Common-law (available as of 1992)
  • ‘W’ –   Widowed
  • ‘D’  –   Divorced
  • ‘A’  –   Separated
  • ‘S’  –   Single
•  The marital status variable is not considered to be reliable because it appears to be subjective. Better indicators of marital status may be the family type variable (FCMP_) and the description of the individual variable (INDFL). 
• Derived from: Personal information section, T1 tax form (1982 to present) 
• LAD: MSTCO   I   character

LAD identification number (LIN__)

(1982 to present)

• Derived from: LAD processing, T1 tax form (1982 to present) 
• LAD: LIN__   I, P

Language of correspondence, English or French (LNGCO)

(1982 to present)

• Definition: The official language code, either ‘E’: English or ‘F’: French.
• Prior to 1995, it is language of the form that the taxfiler submits. It is not necessarily a good indicator of language spoken by the taxfiler.
• From 1995 to present, it is language of correspondence requested by the taxfiler.
• Derived from: Canada Revenue Agency Processing of T1 Tax Form
• LAD: LNGCO   I, P  character

Individual description code - sex; age; imputed; marital status (INDFL)

(1982 to present)

• Definition: The Description of the individual is a numeric code that is assigned to individuals. 
• Following is a list of the codes and their meaning: 
  1. Male, adult, taxfiler, married or common law
  2. Male, adult, non-taxfiler (imputed individual), married or common law
  3. Female, adult, taxfiler, married or common law
  4. Female, adult, non-taxfiler (imputed individual), married or common law
  5. Child taxfiler
  6. Non-taxfiling (imputed) child. (Only available from 1993 to present)
  7. Adult, taxfiler, lone parent
  8. Non-family person, taxfiler
• If an individual dies in a given year, his or her status prior to death is defined in this variable. 
• There is no restriction on the ages of children. A child is defined as anyone who is single and living with one or both parents. For example, a 50 year-old child may be living with a 70 year-old parent. This family would be classified as lone-parent. 
• Derived from: LAD processing 
• LAD: INDFL   I, K

Low income status - total income before tax (LIMXT)

(1982 to present)

• Definition: The Low income status flag identifies low income individuals and families according to the low income measure (LIM).

• LAD: LIMXT   I

Low income status - total income after tax (LIMAT)

(1982 to present)

• Definition: The Low income status flag identifies low income individuals and families according to the low income measure (LIM).

• LAD: RTNTP   I

Social insurance number, change code (SINCH)

(1982 to present)

• Definition: This variable indicates an individual’s social insurance number (SIN) has changed. As described in LIN definition, for a temporary SIN the first digit is 0 or 9 and for a permanent SIN the first digit is within 1 and 8. There are two kinds of change, one based on status change: for example if the visa student who has been issued a temporary SIN becomes a landed immigrant he must reapply for a permanent SIN. The other is because of the issuance of a new SIN to replace a previous SIN of the same class (temporary or permanent).
• Following are the possible codes:
  • ‘0’ –  no change
  • ‘1’ –  change from temporary to permanent
  • ’2’ –  new temporary SIN
  • ‘3’–  new permanent SIN
• Derived from: LAD processing.

(1982 to present)

• Definition: This variable indicates the province, territory or CIDA assignment (External Aid) in which the taxfiler is reputed resident on December 31^st of the tax year. When this residency information is missing, the postal code is used to construct the province of residence. At times, the postal code may also be missing. When this occurs, the family postal code is used to derive this field. For imputed spouses, the PRCO of the tax-filing spouse is assigned to the imputed spouse.

Province of residence (PR___)

(1982 to present)

• Definition: The variable PR uniquely identifies provinces and territories using the Standard Geographical Classification (SGC) and the Postal CodeOM Conversion File (PCCF). The SGC is Statistics Canada's main classification of geographic areas in Canada. It is designed to classify statistical information by geographic areas. The classification consists of four levels: geographical regions of Canada, provinces and territories, census divisions (such as counties and regional municipalities) and census subdivisions (such as municipalities). The four geographic levels are hierarchically related.

Census Division (CD**_)

(1982 to present)

• Definition: Census division (CD) is the general term for provincially legislated areas (such as county, “municipalité régionale de comté” and regional district) or their equivalents. Census divisions are intermediate geographic areas between the province/territory level and the municipality (census subdivision). A census division is a group of neighbouring municipalities joined together for the purposes of regional planning and managing common services (such as police or ambulance services). These groupings are established under laws in effect in certain provinces of Canada.
• For example, a census division might correspond to a county, les municipalités régionales de comté or a regional district. In other provinces and the territories where laws do not provide for such areas, Statistics Canada defines equivalent areas for statistical reporting purposes in cooperation with these provinces and territories. Each CD is identified by a unique four-digit code including the code of the province (first two-digits) and the CD code (third and fourth digits). For example:

  • Census Division
    Table summary
    This table displays the results of Census Division . The information is grouped by PR-CD code (appearing as row headers), CD name and type (appearing as column headers).

    PR-CD code	CD name and type

• LAD: CD11_/CD06_/CD01_/CD96_/CD91_/CD86_/CD81_   I, F

Census Division - unique (XCD**_)

(1982 to present)

• Definition: This variable incorporates geographic codes from other levels of geography (for example, province) to obtain a unique census division (CD) code. The variable utilizes census geography information applicable to the year in which the variable is created. Users should be aware that census geography information changes over time, being updated with each new census. In addition, postal code boundaries do not correspond perfectly with census geography boundaries. For additional information please consult the most recent CD variable using census geographies (for example: CD06_). 
• Derived from: PCONV file from Geography Division and ISD geography conversion file
• LAD: XCD11_/XCD06_/XCD01_/XCD96_/XCD91_/XCD86_/XCD81_   I, F

Census sub-division (CSD**)

(1982 to present)

• Definition: A census subdivision (CSD) is the general term applied to municipalities (as determined by provincial legislation) or their equivalent, for example, Indian reserves, Indian settlements, and unrecognized territories. Each CSD is identified by a unique seven-digit code including the code of the province (first two-digits), the last two-digits of the CD code (third and fourth digit) and a three-digit code for the Census Subdivision. For example:

  • Census sub-division
    Table summary
    This table displays the results of Census sub-division . The information is grouped by PR-CD-CSD code (appearing as row headers), CSD name and type (appearing as column headers).

    PR-CD-CSD code	CSD name and type

• LAD: CSD11/CSD06/CSD01/CSD96/CSD91/CSD86/CSD81   I, F

Census sub-division - unique (XCSD**)

(1982 to present)

• Definition: This variable incorporates geographic codes from other levels of geography (for example, province) to obtain a unique census sub-division (CSD) code. The variable utilizes census geography information applicable to the year in which the variable is created. Users should be aware that census geography information changes over time, being updated with each new census. In addition, postal code boundaries do not correspond perfectly with census geography boundaries. For additional information please consult the most recent CSD variable using census geographies (for example: CSD06). 
• Derived from: PCONV file from Geography Division and ISD geography conversion file 
• LAD: XCSD11/XCSD06/XCSD01/XCSD96/XCSD91/XCSD86/XCSD81   I, F

Census Metropolitan Area (CMA**)

(1982 to present)

• Definition: A census metropolitan area (CMA) or a census agglomeration (CA) is formed by one or more adjacent municipalities centred on a large urban area (known as the urban core). A CMA must have a total population of at least 100,000 of which 50,000 or more must live in the urban core. A CA must have an urban core population of at least 10,000. To be included in the CMA or CA, other adjacent municipalities must have a high degree of integration with the central urban area, as measured by commuting flows derived from census place of work data.
• If the population of the urban core of a CA declines below 10,000, the CA is retired. However, once an area becomes a CMA, it is retained as a CMA even if its total population declines below 100,000 or the population of its urban core falls below 50,000. The urban areas in the CMA or CA that are not contiguous to the urban core are called the urban fringe. Rural areas in the CMA or CA are called the rural fringe.
• When a CA has an urban core of at least 50,000, it is subdivided into census tracts. Census tracts are maintained for the CA even if the population of the urban core subsequently falls below 50,000. All CMAs are subdivided into census tracts. For Census metropolitan area 2006 there are 33 census metropolitan areas in Canada. Each CMA or Census Agglomeration (CA) in Canada is identified individually by the two-digit code of the province followed by a unique three-digit code for the CMA/CA. For example:

  • Census Metropolitan Area
    Table summary
    This table displays the results of Census Metropolitan Area. The information is grouped by PR-CMA/CA code (appearing as row headers), CMA/CA name (appearing as column headers).

    PR-CMA/CA code	CMA/CA name

    35 505	Ottawa - Gatineau CMA (Ont.)
    47 840	Lloydminster CA (Sask.)
    48 840	Lloydminster CA (Alta.)

Census Metropolitan Area - unique (XCMA**)

(1982 to present)

• Definition: This variable incorporates geographic codes from other levels of geography (for example, province) to obtain a unique census metropolitan area (CMA) code. The variable utilizes census geography information applicable to the year in which the variable is created. Users should be aware that census geography information changes over time, being updated with each new census. In addition, postal code boundaries do not correspond perfectly with census geography boundaries. For additional information please consult the most recent CMA variable using census geographies (for example: CMA06). 
• Derived from: PCONV file from Geography Division and ISD geography conversion file 
• LAD: XCMA11/XCMA06/XCMA01/XCMA96/XCMA91/XCMA86/XCMA81   I, F

Census Tract (CT**_)

(1982 to present)

• Definition: Census tracts (CTs) are small geographic units representing urban or rural neighbourhood-like communities in CMAs or CAs (with an urban core population of 50,000 or more at the previous census). Each census tract is assigned a seven-character numeric 'name' (including leading zeros, the decimal point and trailing zeros). To uniquely identify each census tract in its corresponding census metropolitan area or tracted census agglomeration, the three-digit CMA/CA code must be added to and precede the CT 'name'. For example:

  • Census Tract
    Table summary
    This table displays the results of Census Tract . The information is grouped by CMA/CA code - CT name (appearing as row headers), CMA/CA name (appearing as column headers).

    CMA/CA code - CT name	CMA/CA name

Census Tract - unique (XCT*)

(1982 to present)

• Definition: This variable incorporates geographic codes from other levels of geography (for example, province) to obtain a unique census tract (CT) code. The variable utilizes census geography information applicable to the year in which the variable is created. Users should be aware that census geography information changes over time, being updated with each new census. In addition, postal code boundaries do not correspond perfectly with census geography boundaries. For additional information please consult the most recent CT variable using census geographies (for example: CT06).
• Derived from: PCONV file from Geography Division and ISD geography conversion file
• LAD: XCT11_/XCT06_/XCT01_/XCT96_/XCT91_/XCT86_/XCT81_   I, F

Postal code (PSCO_)

(1982 to present)

• Definition: The postal code is a six-character, alphanumeric code that locates the point of delivery of mail addressed to post office customers in Canada. The code itself is divided into the forward sorting area (FSA, first three characters) and the local delivery unit (LDU, last three characters). In most applications, the postal code from the family aggregate level should be used instead of the individual aggregate level.  
• The family postal code is a more reliable variable as there is a higher probability of having information in this field because the postal code can be selected from those within the family unit. Also, there is an increased likelihood that a residential and not a business address will be selected for the family postal code. When analyzing migration patterns, the individual postal code is recommended. Note that there is a Nunavut family postal code flag for Nunavut (NUNAV). 
• Derived from: Personal Identification Section, T1 tax form (1982 to present) 
• LAD: PSCO_   I, F      character

Area size code (ASR__)

(1982 to present)

• Definition: An area size code classifies segments of the population by grouping them into specific urban size ranges or within a rural area represented by a code. Within T1 Family File (T1FF) and LAD each postal code has a corresponding Area Size Rank (ASR) code. The population counts for postal codes were aggregated by ASR code to the Canada level. The resulting variable yields six categories of area size:
  • 1 – Urban area, population 500,000+
  • 2 – Urban area, population 100,000 – 499,999
  • 3 – Urban area, population 30,000 – 99,999
  • 4 – Urban area, population 15,000 – 29,999
  • 5 – Urban area, population 1,000 – 14,999
  • 6 – Rural area, population less than 1,000+

• Definition: A unique identification number for each First Nation settlement within Canada.
• Derived from: CRA calculation
• LAD: FNSTLN_   I, F, P

Canada Post mode of delivery (DLMD_)

(1982 to present)

• Definition: The delivery mode is a classification of different types of mail delivery in Canada. This variable can be used to identify residential, non-residential, urban, urban fringe, and rural addresses. The delivery modes, as of 2007, are:
  • A = letter carrier delivery to domestic address
  • B = letter carrier delivery to apartment building
  • E = letter carrier delivery to commercial office
  • G = specific large volume receiver with pick up arrangements
  • H = rural route delivery
  • J = general delivery
  • K = post office box delivery with the postal code identifying a group of boxes
  • M = post office box delivery with the postal code identifying one box (i.e. large volume receiver)
  • N = unknown
  • R = miscellaneous
  • T = suburban service delivery
  • W = rural postal code
  • X = mobile route delivery
  • Z = retired, for which delmode, while active, is unknown
• Delivery modes "W" and "N" are assigned by the Income Statistics Division; the others come directly from Canada Post. This division assigns a "W" for rural postal codes whenever the second position of the postal code is a zero.
• An "N" is assigned for an unknown delivery mode for very old postal codes. This division does not accept Canada Post's "Z" delivery mode unless unavoidable, and instead retains the delivery mode type when the postal code was in use.
• Postal codes are combined by delivery to represent FSA publication delivery modes (PBDLMD).

• Canada Post mode of delivery

Immigration

From Tax Form

Entry date of immigrant (ENTDT)

(1982 to present)

• Definition: Date of Entry refers to the date that a non-Canadian person immigrant arrived in Canada. Taxfilers who became Canadian residents during the tax year must report the day and month that they entered Canada. It is reported in the personal information section of the tax return. ENTYDT contains the year, month, and day of arrival (YYYYMMDD).
• Derived from: Personal Information Section of Revenue Canada T1 tax form
• LAD: ENTDT   I

Date of departure of emigrant (DEPDT)

(1982 to present)

• Definition: Date of Departure refers to the date that a Canadian resident left Canada. Taxfilers who ceased to be Canadian residents must report the day and month of the tax year that they left Canada. It is reported in the personal information section of the tax return. This variable contains the year, month, and day of departure (YYYYMMDD).
• Derived from: Personal Information Section of Canada Revenue Agency T1 tax form
• LAD: DEPDT   I

From IMDB (Immigration Database)

Immigrant category (IMCAT)

(1980 to 2014)

• Definition: This variable specifies the category of immigrant from those of the Immigration Act. This field allows the user to group data from the Longitudinal Immigration Database (IMDB) by defined categories. The codes distinguish first and foremost between types of immigrant, but also define whether or not the immigrant is the principle applicant, whether the request was filed abroad or in Canada and whether or not a special program was resorted to. This variable is a broader categorization than the LAD variable CATIM.
• The corresponding codes are:

Immigrant's country of birth (PAYSN)

(1980 to present)

• Definition: The code for the country of birth.
  Note: The country of birth should be accurately identified even though that country may no longer exist or be recognized as a nation state.  See the listing under the Immigrant’s country of citizenship at landing (PAYSC) variable for the country codes associated with this variable.

Immigrant's country of citizenship at landing (PAYSC)

(1980 to present)

• Definition: A code representing the immigrant's country of citizenship at the time they were granted permanent residence in Canada. This code may, or may not be, the same as the country of birth or last permanent residence. Country codes are as follows:

Immigrant's country of last permanent residence (PAYSR)

(1980 to present)

• Definition: This variable is based on the country of last permanent residence, meaning the country where the immigration applicant has resided on a permanent (or de facto permanent) basis for one year or more.  De facto permanent applies to residence in a country that never confers permanent residence (such as "illegal" Chinese in various South East Asian countries) or only after a long period (such as Switzerland). 
• Exceptions:
  • a)  For a Convention Refugee (CR) or member of any Designated Class (DC), CLPR means the country from which the applicant fled.  In the case of Political Prisoners and Oppressed Persons (PPOP) Designated Class, CLPR may be the country in which the refugee is currently living (e.g. Special Programs such as Polish Detainee Program, Salvadorian Political Prisoners and Guatemalan PPOP).
  • b)  Regardless of the time a person has resided in a country, if that person's status is of a temporary nature (foreign student, guest worker, long term visitor) CLPR will be the country where the person resided permanently prior to entering the country of present residence.
• CLPR for dependent children of CR/DC applicants should be coded the same as the CLPR of the principal applicant regardless of the country of birth or residence of the child.  This applies only to CR and DC cases for dependent children and does not affect the CLPR coding for spouses of CR and DC applicants, which should continue to be determined according to item 10.20(2).
• The following countries have been regrouped or restructured compared to the original CLPR variable on the IMDB:  England, Scotland, Wales, Northern Ireland and the Channel Islands are classified together under the code for the United Kingdom.  Portugal and Azores have separate codes.  Spain and Canary Islands have separate codes.

• This variable exists for all LAD selected individuals.  If they are not immigrants landed between 1980 and the present, the value will be missing or zero. It is therefore possible to identify all recent immigrants and compare them with the non-recent immigrants (this population includes the Canadian-born, the immigrants landed in other years and all non-permanent residents).
• Derived from: IMDB variable LNDYR
• REG: LNDYR   I

Master categorization of immigrant categories (CATIM)

(1980 to 2013)

• Definition: This field is a ‘Master categorization’ of immigrant categories which allows the user to group IMDB data by custom categories. In layperson’s terms, the computer program constructs the categories by translating ‘old Act’ categories to ‘new Act’ ones and distinguishing between immigrants whose applications were processed abroad or in Canada, whether or not they fall under ‘Special Programs’ and whether they are Principle Applicants or not. This ‘Master Categorization’ serves as the basis for grouping specific categories into broader groupings, e.g., all applications processed abroad versus processed inland and immigrants processed through ‘Special Programs’. 
  • The first three characters represent code for the immigrant’s category of immigration as defined in the Immigration Act.
  • The fourth character is 1 for those who had their VISA issued abroad and 0 for those who had their VISA issued inland.
  • The fifth character is 1 if the immigrant was not processed through a special program and 0 if the immigrant was processed through a special program.
  • The sixth character indicates family status, values are:
    1. if the immigrant is the principle applicant;
    2. if the immigrant is a spouse;
    3. if the immigrant is a dependent (excluding those processed as a result         regulation J88 since June 1991);
    4. if the immigrant is a dependent (including only those processed as a result of regulation J88 since 1991);
    5. definition still to be provided by CIC; and

• Definition: This codes the main sub-sector of paid employment activity for the individual according to 3-digit North-American Industry Classification System (NAICS) of the employers. The data is derived from a linkage between the T4 slips issued for the individual and Statistics Canada’s Business Register. For a business with operations in several industrial sub-sectors, the principal sub-sector is chosen (this may not be the sector of activity of the individual). The employment earnings associated with each T4 slip are aggregated by 3-digit NAICS and the two top sub-sectors of paid-employment are stored in Main principal industry sub-sector of employers (NAIC1) and Secondary principal industry sub-sector of employers (NAIC2). A count of the different industries appearing on at least one slip for the individual shows up in Principal industry sub-sectors of employers, number of (NAICC). The T4 slips issued to individual, number of (T4CNT) variable is also available.

Standard industrial classification code - CRA coded (SICCD)

(1986 to 1992)

• Definition: In the Personal Information Section, taxfilers were asked to state the type(s) of work or occupation(s) that they had in the given year. For some taxfilers, primarily the self-employed, the Canada Revenue Agency classified this information by industry using the Standard Industrial Classification Coding System (SICCD). The SICCD classifies establishments engaged in similar types of activities in relation to similar goods and services. Examples are logging camps, coal mines, clothing factories and laundries. This classification has been developed primarily for establishments that are separate operating entities. The degree of accuracy for this field is not known because this field is seldom used. Starting in 2000, more industry information is available for people who receive a T4 slip from an employer. Consult Main principal industry sub-sector of employers (NAIC1) and Secondary principal industry sub-sector of employers (NAIC2).

• Derived from: LAD processing
• LAD: FSIZE   I

Family identification number (FIN__)

(1982 to present)

• Definition: The family identification number (FIN) is a unique number assigned to each family. Each member within the family is assigned the same number. It is used to identify individual census families that have been created in a specific year. This number is not necessarily the same from one year to the next because it is randomly chosen from either parent if the two exist.
• Derived from: T1FF processing
• LAD: FIN__   I

Number of members with a SIN (NWSIN)

(1982 to present

• Definition: This variable is a count of the number of individuals within a family (file type = F) or a couple (file type = P) that have a social insurance number (SIN). The SIN is the basis of selection of individuals into the LAD. The probability of a T1FF family (couple) being represented in the LAD is proportional to the number of individuals within the family (couple) that have a SIN. The greater the numbers of people within a family (couple) that have a SIN, the greater the probability this family (couple) will be selected. In addition to increasing the probability of being selected, families or couples with more than one SIN also have a probability of being selected more than once within the LAD.
• The Number of members with a SIN variable can be used to equalize the probability of selecting families or couples into a sample. Please see LAD staff regarding the methods of equalizing the representation of families (couples) within a sample.

• Definition: Family flag is a code that is assigned to every record. It identifies where the individual was matched within the family system, under what conditions, and whether or not the individual in a given family is an adult or a child. This variable is not intended to be used as an indicator of marital status.
• The following codes have been assigned:
  • ‘0’  Unmatched filer
  • ‘1’  Married couple
  • ‘2’  Declared married, filers living at the same address
  • ‘3’  Widowed/deceased, one of the spouses is deceased
  • ‘4’  Married couple, neither person lists a spousal SIN, filers matched by address
  • ‘5’  Formerly married
  • ‘6’  Tax-filing child
  • ‘7’  Non-filing spouse, imputed record
  • ‘8’  Non-filing child, imputed record
  • ‘9’  Common-law couple with at least one spouse reporting
  • ‘10’  Deceased/deceased couple, deceased filer matched with deceased filer

Family Weight Variable - LAD (FAMWGT)

(1982 to present)

• Definition: The LAD Family weight is to be used to provide estimates of the population of taxfiling families. Estimates produced with this weight are comparable to those from the T1 Family File (T1FF). In order to obtain correct family taxfiler estimates when applying the LAD Family weight, users must ensure two things:
  1. The family weight variable is only to be applied to LAD variables ending with the letter 'F' character aggregate (for example, XTIRC_F);
  2. In order to obtain correct family estimates users must select only one record from each family. That is, when performing their analyses users must ensure that for each FIN__i there is only one associated LAD record (one LIN__i). Since the LAD is a random sample it is possible that more than one member from the same family will appear on the LAD.

• LAD: SSFLG    I         character

Child or Dependant Related

Children, ages of the seven youngest (KID*_)

(1982 to present)

• Definition: The ages of the seven youngest children are available on the LAD file. Another file, the KIDS file, contains the ages of all the children in the families on the LAD. Taxfiling children's ages are calculated by subtracting the child's year of birth from the tax year of the data. Non-taxfiling children’s ages were imputed in 1982 and 1983. From 1984 to date, most of the ages of children have not been imputed. The major sources of information on ages for children are as follows: from 1984 to 1992, Family Allowance and from 1993 to date, the Child Tax Benefit file.
• Please note that children may be any age, i.e. a 40 year-old child may be living with a 60 year-old parent. This variable is considered as a cross-sectional variable rather than a longitudinal variable because there are inconsistencies from year to year in children’s ages. The order in which the children are outlined on the file is from the youngest (most recent child) to the seventh youngest.

Children, number of children under age 18 (CLT18_)

(2007 to present)

• Definition: The number of children under age 18 at the end of the taxation year for whom the children amount deduction was claimed. For 2007, and later years, a personal amount may be claimed for each child under age 18 at the end of the taxation year. The amount is independent of any income the child may have; that is, it is not reduced by any amount if the child has income of his or her own.

Children, total number by specific year of age (TNK**)

(1982 to present)

• Definition: These variables provide the total number of children that each tax filer may have, by the specific age for those children, ages 0 through to 18 years. A single additional variable provides information for those filers with children aged 19 years and older. A value of 0 (zero) for any variable indicates that the filer does not have a child of that age. A value of 1 or greater indicates that the filer has that specific number of children of the particular age variable. For example, if a filer has three children, one aged 6 months and two other children aged 3 years, then for that filer the variable TNK00 would have a value of 1, and the variable TNK03 would have a value of 2. For further information please also see variable KID_ “Children, total number in family”.

Children, total number in family (TNKID)

(1982 to present)

• Definition: The total number of children in a family is identified in this field. A child is defined as someone who is single and living with one or both parents. Please note that children may be any age, i.e. a 40-year-old child may be living with a 60-year-old parent. 
• The number of children might have changed in a family over the 2005-2008 period due to improvements to the T1FF process of identifying children and the introduction of the Children Fitness tax credit (CFA) and Children Amount Deduction (CHAD) in 2007 and the Universal Child Care Benefit program in 2006 allowing for the identification of more children.  These changes have resulted in improved coverage of children in the T1FF.  The impact of these changes is most notable in the count of imputed children from lone-parent families although it is not possible to distinguish the precise impact of the improvements separately from normal year-to-year change.
