Urban planning, social policy, and local marketing strategies require a comprehensive understanding of regional socio-economic characteristics. The T1 Family File (T1FF) data, available for low levels of geography, can contribute significantly to this knowledge. These data will be a valuable aid to anyone assessing the sociological and financial status of residents in the geographic area of interest to them.

The T1FF data includes tables on census families, individuals and seniors. These tables are compiled from information obtained through annual personal income tax returns and is updated annually.

For simplicity, this documentation has been divided into four sections:

  • The first section deals with the source of the data, its vintage and accuracy and how the data are presented to maintain confidentiality.
  • The second section on data tables includes notes of explanation and describes the format of the data tables.
  • The glossary, in the third section, will provide the data user with definitions of the terms used in this documentation.
  • The fourth section contains an explanation of the geographic levels available.
