This article develops computational tools, called indicators, for judging the effectiveness of the auxiliary information used to control nonresponse bias in survey estimates, obtained in this article by calibration. This work is motivated by the survey environment in a number of countries, notably in northern Europe, where many potential auxiliary variables are derived from reliable administrative registers for household and individuals. Many auxiliary vectors can be composed. There is a need to compare these vectors to assess their potential for reducing bias. The indicators in this article are designed to meet that need. They are used in surveys at Statistics Sweden. General survey conditions are considered: There is probability sampling from the finite population, by an arbitrary sampling design; nonresponse occurs. The probability of inclusion in the sample is known for each population unit; the probability of response is unknown, causing bias. The study variable (the y-variable) is observed for the set of respondents only. No matter what auxiliary vector is used in a calibration estimator (or in any other estimation method), a residual bias will always remain. The choice of a "best possible" auxiliary vector is guided by the indicators proposed in the article. Their background and computational features are described in the early sections of the article. Their theoretical background is explained. The concluding sections are devoted to empirical studies. One of these illustrates the selection of auxiliary variables in a survey at Statistics Sweden. A second empirical illustration is a simulation with a constructed finite population; a number of potential auxiliary vectors are ranked in order of preference with the aid of the indicators.

Release date: 2010-12-20 - 3. Incomes from Owner-occupied Housing for Working-age and Retirement-age Canadians, 1969 to 2006 ArchivedArticles and reports: 11F0027M2010066Geography: CanadaDescription:
Using data from the Survey of Household Spending and from its predecessor, the Survey of Family Expenditures, this paper investigates the relative incomes of retirement-age and working-age Canadians from 1969 to 2006, taking into account both explicit household income and the implicit income generated by owner-occupied housing. Over this 37-year period, the explicit incomes of retirement-age households increased at a more rapid pace than those of working-age households. Implicit income from owner-occupied housing also increased rapidly during this time, matching the rate at which the explicit income of retirement-age households increased. On average, this implicit source of earnings raised the incomes of retirement-age households (aged 70 and over) by 16%. Taking both forms of income into account, the incomes of retirement-age households (aged 70 and over), relative to the incomes of working-age households (aged 40 to 49), increased from 45% in 1969 to 59% in 2006. During this period, Canadians invested in housing assets that provided additional income upon retirement.

Release date: 2010-09-08 - 6. Income replacement during the retirement years ArchivedArticles and reports: 75-001-X201010811331Geography: CanadaDescription:
This article examines the extent to which family income of individuals in their mid-fifties is 'replaced' by other sources of income during the retirement years. It does so by tracking various cohorts of tax filers as they age from their mid-fifties to their late seventies and over. Earlier work examined this question for the 50% of the population with strong labour market attachment during their mid-fifties. This paper extends that work to include 80% to 85% of the population.

Release date: 2010-08-16 - Articles and reports: 11F0019M2010328Geography: CanadaDescription:
This paper examines the extent to which family income during working years is replaced during the retirement years. It does so by tracking cohorts as they age from their mid-50s to their late 70s, using a taxation-based longitudinal data source that covers 26 years from 1982 to 2007. Earlier work by the same authors examined this question with respect to the 50% of the population with strong labour force attachment during their mid-50s. This paper extends that work to include almost all Canadians (80% to 85% of the population). The adult-equivalent-adjusted family income available to the median Canadian during his or her late 70s is about 80% of that observed when the same person was in his or her mid-50s (a replacement rate of 0.8). Replacement rates in retirement are negatively correlated with income earned around age 55. Median replacement rates are 1.1 among individuals in the bottom income quintile, 0.75 in the middle quintile, and 0.7 in the top quintile. In retirement, public pensions and other transfers more than replace earnings and other income of bottom quintile individuals. However, some individuals have very low replacement rates. For example, 20% of individuals in the middle income quintile had replacement rates below 0.6. More recent cohorts had higher family incomes in retirement than did earlier cohorts as a result of higher earnings and private-pension income.
Release date: 2010-07-29 - Articles and reports: 11F0027M2010064Geography: CanadaDescription:
This paper estimates the implicit income generated by the home equity of working-age and retirement-age households. In so doing, it expands our understanding of Canadians' preparation for retirement by taking into account the services that homeowners realize as a result of having invested in their homes. On the basis of both the 2006 Survey of Household Spending and the 2006 Census of Population, we find that housing services make an important contribution to household income. When estimates of the services provided by the equity invested in housing are added to traditional estimates of income, the income of retirement-age households is increased by 9% to 12% for those in the 60-to-69 age class and by 12% to 15% for those in the 70-plus age class. In turn, this additional income reduces the difference in income between working-age and retirement-age households that own their own homes. According to the Survey of Household Spending, net incomes decline by about 45% between the peak household earning years and the 70-plus retirement-age class. This figure is reduced to 42% when the contribution of housing services is taken into account. The Census provides a similar picture: the gap in incomes is 38% when net income alone is considered and 35% when one accounts for housing services.

The 2003 National Assessment of Adult Literacy (NAAL) and the international Adult Literacy and Lifeskills (ALL) surveys each involved stratified multi-stage area sample designs. During the last stage, a household roster was constructed, the eligibility status of each individual was determined, and the selection procedure was invoked to randomly select one or two eligible persons within the household. The objective of this paper is to evaluate the within-household selection rules under a multi-stage design while improving the procedure in future literacy surveys. The analysis is based on the current US household size distribution and intracluster correlation coefficients using the adult literacy data. In our evaluation, several feasible household selection rules are studied, considering effects from clustering, differential sampling rates, cost per interview, and household burden. In doing so, an evaluation of within-household sampling under a two-stage design is extended to a four-stage design and some generalizations are made to multi-stage samples with different cost ratios.
Release date: 2010-06-29 - 9. Gross flow estimation in dual frame surveys ArchivedArticles and reports: 12-001-X201000111248Description:
Gross flows are often used to study transitions in employment status or other categorical variables among individuals in a population. Dual frame longitudinal surveys, in which independent samples are selected from two frames to decrease survey costs or improve coverage, can present challenges for efficient and consistent estimation of gross flows because of complex designs and missing data in either or both samples. We propose estimators of gross flows in dual frame surveys and examine their asymptotic properties. We then estimate transitions in employment status using data from the Current Population Survey and the Survey of Income and Program Participation.
Release date: 2010-06-29 - 10. A comparison of sample set restriction procedures ArchivedArticles and reports: 12-001-X201000111249Description:
For many designs, there is a nonzero probability of selecting a sample that provides poor estimates for known quantities. Stratified random sampling reduces the set of such possible samples by fixing the sample size within each stratum. However, undesirable samples are still possible with stratification. Rejective sampling removes poor performing samples by only retaining a sample if specified functions of sample estimates are within a tolerance of known values. The resulting samples are often said to be balanced on the function of the variables used in the rejection procedure. We provide modifications to the rejection procedure of Fuller (2009a) that allow more flexibility on the rejection rules. Through simulation, we compare estimation properties of a rejective sampling procedure to those of cube sampling.
