1. Working with Taxfiler (T1FF) Data Wayne Chu Planning Analyst Social Development, Finance & Administration, City of Toronto Toronto CDP Face-to-Face, September 11, 2014 1

2. What is Taxfiler Data? Income data collected from all Canadians who filed a T1 tax return. Taxfilers from the same family are linked based on common links (e.g. spousal SIN, name, address, Canada Child Tax Benefit data. Taxfiler provides users with income statistics by family size, age and sex.

5. What other data is available? In addition to the Family tables, the following datasets are also available on Canadian taxfilers: Financial Data and Charitable Donations Neighbourhood Income and Demographics Seniors

6. Data Quality Most Canadians with income file T1 tax returns, so the coverage of Taxfiler data is good. Toronto population count is 2% lower in the T1FF as compared to the Census Count of children is 5% higher in the T1FF in Toronto as compared to the 2011 Census. This is partly due to double-counting (e.g. children in single-parent families counted twice). 6

7. Advantages Taxfiler is based on a complete database rather than a a sample. Contains fewer problematic quality issues than the NHS. Data is available annually and at a low-level of geography (Census Tracts) Disadvantages Cannot be cross-tabulated with ethnocultural data. Family data is derived and not based on actual reporting of family structure. Statistics Canada ensures data is consistent with within-year control totals, but does not actively check cross-time consistency. 7 Taxfiler Advantages & Disadvantages

8. LICO is no longer offered as a standard product LIM-AT does not consider relationship between income and necessities Voluntary and therefore not comparable to previous Censuses Many users unfamiliar with this dataset Data cannot be cross-tabbed with other sociodemographic variables beyond age, sex and family structure Taxfiler “families” are derived and therefore may double count some individuals (e.g. children in lone parent families) 8 NHS and Taxfiler National Household Survey T1FF (Taxfiler)

9. DEFINITION LICOs identify those who are substantially worse off than the average income thresholds are determined by analysing expenditure data threshold = HH spending 20% or more of their income on necessities than the average HH HH that devote a larger share of gross income to basic necessities than the average, would fall into the category of “straightened circumstance” as the name implies, it is a low income “cut-off” not a “poverty line” Low-Income Cut-off (LICO) 9

10. DEFINITION those living in families that have an after-tax income lower than 50% of the median income for all families in a given year Personal income is adjusted for household size. as the name implies, it is a low income “measure” not a “poverty line” Low-Income Measure (LIM) 10
