Survey of Labour and Income Dynamics

What is the Survey of Labour and Income Dynamics?

The Survey of Labour and Income Dynamics (SLID) is a longitudinal household survey designed to follow the same participants for several years. The survey gathers information on the economic well-being of individuals and families, and the changes that influence this well-being. SLID also collects information about other related topics such as education and disabilities.

What do you mean "longitudinal" survey?

Most surveys just provide a "snapshot" look at the group they are surveying, that is, a picture of the situation at a specific point in time. A "longitudinal" survey involves surveying the same group of people over a longer period of time. In the case of SLID, people are contacted once a year for six years.

Conducting the survey over a period of a few years not only provides the necessary information about changes that occur, but also shows the effect of those changes. For instance, does returning to school result in new jobs or promotions, and if so, how long after the retraining? How is income affected by events like marriage, the birth of a child, divorce, loss of a job, a job promotion, etc.

How is the information collected?

Interviewers conduct the interview by telephone. Interviewers use a computer to conduct the interview so the information is recorded immediately.

How long am I in this survey?

Currently, respondents are selected for a survey period of six years.

Who is surveyed?

Approximately 37,000 households are surveyed each year throughout all ten provinces. Information is collected from all household members 16 years of age and older. Even if the member leaves the household, all efforts are made to stay in touch with that person in order to have complete information over the survey period. In fact, moving in and out of a household is the type of change which is very relevant to SLID because moving has an important effect on other household members and their finances. On the other hand, people who do not move or change jobs are also important to the survey, as we are looking for information about all Canadians.

It is also important that SLID includes all types of households, whether they consist of parents with their children, seniors only, students only, or one person living alone. Each and every household is typical of many others like it and some users of SLID data will be interested in working-age respondents while others are looking at retirement or other seniors’ issues.

Is my participation voluntary?

Yes. Your participation in this survey is voluntary. However, since each household represents many other similar households nationally and provincially, it is important that the selected households participate. This ensures that accurate information is available for all provinces and at the national level. For scientific reasons, we cannot replace your household with another one. Every household that does not participate reduces the amount of data that we collect.

Why was my household selected?

It would be very expensive, and not very practical to survey every household in Canada. Instead, Statistics Canada uses a statistical method called sampling. It is an established way to determine characteristics of an entire population by surveying only part of the population. Every region is included with people from all walks of life.

During this process, your address was initially chosen and not you personally. The people who live at the selected addresses at the start of the survey become the sample and then those people continue in the survey even if they move to another address. As others move in with you, they too become eligible for the survey. The people in your household now represent hundreds of other Canadians in similar households.

To ensure that the sample is an accurate reflection of the population as a whole, both nationally and provincially, it is important to have the participation of all selected respondents.

Is the information my household provides confidential?

Statistics Canada recognizes the trust that respondents place in us to protect their data. That is why we follow strict rules to ensure the confidentiality of your information and your privacy.

Under the Statistics Act, all Statistics Canada employees must take an oath of secrecy. Employees are personally liable to imprisonment or a fine if they divulge any information. Only employees who need to work with the data files have access to them. When survey data are released, your answers are combined with those of other participants and we do not disclose any information that could identify you. Your individual information will never be given to any other government agency - not even the courts, the police or the Canada Revenue Agency.

Furthermore, this information cannot be made available under any other law, not even the Access to Information Act.

Why do you ask for my permission with respect to data linkage?

During the interview Statistics Canada will ask your permission to access your information collected under the Income Tax Act; this makes the survey shorter since it eliminates the need to ask income questions.

In case you move and we are unable to reach you for a further interview, Statistics Canada would like your permission to access your provincial driver's license files. These files will only be used to find your new address and phone number.

The Statistics Act requires that the information you provide be kept strictly confidential. No data linkage will be done without your permission.

What type of information does the survey collect?

SLID collects information on the labour force activities during the previous year and information on income and sources of income. It also gathers data affecting the family such as migration, forming a family or its break-up, disabilities, child care expenses and education. Household members may respond individually or one person can answer on behalf of the entire household.

How is the information used?

SLID provides information useful to each and every Canadian. For many, life follows a course of school, work, and then retirement. But what happens along the way? Some people marry and have children. For some, divorce or the death of a spouse occurs. Children leave home and some return. When and how does a student become a paid worker? When should you change jobs? What should you do when you lose a job? When you have children, should both partners work? How do you decide when to retire? After you retire, will you have enough income to meet your needs? No matter which path your life follows, many of your decisions and the impact of many events are highly related to your level of income and that of your family. How should government programs be tailored to ensure that everyone needing help gets it? To answer these questions and more, this is where data from SLID come in.

The following are examples of information needed about different groups in our country. This type of information is needed to assess the effectiveness of programs now designed to aid these groups.

Social assistance programs from all levels of government

National Child Tax Benefit program

Government transfers

How many families are living in low income and how has this changed over time?

Do existing programs reduce the number of children who live in low-income families?

How have parental benefits and income programs changed family circumstances?

What is the impact of housing costs on lower-income families? What proportion of their income do they spend on rent?

An estimated 633,000 families were living in low income in 2006, unchanged from 2005. However, families in low income needed on average $7,000 to climb above the low income cut-off, an improvement compared to the 2005 average of $8,000.

About 760,000 children under 18 were living in low income families in 2006, a number unchanged from 2005, but down from the 1.3 million in 1996.

Low income cut-off after-tax for families of 4 persons reached $33216 in cities of more than 500,000 inhabitants in 2006. (i.e. Quebec City and Winnipeg).

For every $100 in total income received by Canadian families in 2006, an average of $7 came from government transfers.

Two-parent families with children saw an increase in the amount of government transfers between 2005 and 2006 in part because of the introduction of the Universal Child Care Benefit which provided families $100 per month for each child under 6. Their median government transfers were $3,300  which was $500 more than the previous year.

Measuring affordability involves comparing housing costs to a household's ability to meet them. One common measure is the shelter cost-to-income ratio (STIR). The 30% level is commonly accepted as the upper limit for affordable housing. Lower-income households spent a higher share of their incomes on shelter and were more likely to surpass the affordability benchmark between 2002 and 2004. In fact, over 80% of people in households exceeding the benchmark fell into the bottom 40% of the income distribution. The median market rent was $8,300 for market renters, which is about 23% of their income. If subsidized renters had paid the median market rent of $8,300 rather than their subsidized rents ($5,000), their median STIR would have been 42% instead of 26%. This helps make their shelter costs much more affordable when compared with their very low median incomes.

Single-parent families

Provincial social assistance programs

How many female single-parent families are living in low income and how has this changed over time?

How many children end up living in low income because of family break-up (divorce or separation)?

What impact do changes in social housing policy have on female single-parent families?

In 2006, 28.2% of female lone-parent families were living in low income down from 29.1% in 2005 and 52.7% in 1996.

A study found that approximately 2% of children from 2003 fell into low income in 2004. For 42% of these children, the main reason was a change in their family environment (for example, parental separation or a new sibling).

57% of female lone-parent families were in households that spent above the affordability benchmark at some point during the 2002 to 2004 period.

Median household income of female single-parent families was $30,500 between 2002 and 2004. They spent about 27% of this on shelter costs.

What impact do shifts in interest rates and drops/increases in stock markets have on the high-income group?

The 20% of families with the highest family after-tax income did not experience a significant increase in their average after-tax income between 2005 ($130,700) and 2006 ($133,900). However, their average after-tax income increased by 27%, the fastest growth over the 1996 to 2006 period.

The 20% of families and unattached individuals with the highest after-tax income in 2006 paid 59.4% of all personal income taxes that year.

In 2006, the average after-tax income was $133,900 for the 20% of families with the highest income (highest quintile).

As a point of comparison, the income of the families in the highest income quintile was about 5.4 times higher than those in the lowest income.

Youth from two-parent families are more likely to go on to postsecondary studies than youth from single-parent families.

Females are more likely to attend university than males.

Canadians who have not completed high school have a higher probability of being exposed continuously to low income than university graduates.

In 2006, almost 10% percent of the population (16-45) had ever received a student loan.

Canadians who had ever received a student loan, on average, borrowed $12,900 and still owed $5,900 at the end of 2006.

Government transfers are higher for seniors than for people of working age.

In 2006, senior families relied less on earnings compare to non-senior families and more on government transfers. For every $100 of total income, they received $46 from government transfers.

Just under half of workers in their 50s and 60s who ended a full-time career job between 1993 and 1997 were working 24 months later. Three in 10 began a new full-time job, while 1 in 10 began a part-time job.

A large proportion of government transfers to senior families were from OAS/GIS/SPA (48%) and CPP/QPP (43%), while the other 9% were allocated to other transfer programs.

Seniors living on their own were 7.0 times more likely to be in low income compared to seniors in economic families.

How has EI benefits changed over time?

The average hourly wages of mothers that delay having children are 17.1% higher than mothers that have children early while wives that delay marriage earn 7.8% more than wives that marry early.

Women comprised 55% of the chronically unemployed population, and the problem was especially acute for single mothers.

In addition, people who had not graduated from high-school were over-represented in the population of the chronically unemployed, as were people who live in Quebec and the Atlantic provinces, members of visible minority groups and people with disabilities.

Overall, unemployed people as a single group averaged 2.2 spells of unemployment of at least 22 weeks each, over the 1993 to 2001 period.

Adults who went back to school and completed a postsecondary certificate generally registered higher gains in earnings than those who did not participate, even when factors such as firm size, occupation, industry, union status, and province were taken into account.

Older men and women who stayed with the same employer while obtaining a postsecondary certificate registered gains in hourly earnings that were 13% and 7% higher respectively than their counterparts who did not go back to school.

15% of the working age population (16 to 64 years of age) was unemployed some time during 2006, and 1.3% was unemployed for the whole year.

Among non-senior families, earnings made up the largest share of income before taxes. For every $100 of total income, families received $93 from market income and $7 was from government transfers. Senior families receiving almost six times as much of their total income from government transfers. For every $100 of total income in 2006, they received $39 from government transfers and $61 from the market.

In 2006, 5.4% of all paid employees earned minimum wage from their main job.

In 2006, 22% of all paid employees took a course related to their job.

For individuals who received EI benefits the average benefit was $5,400 in 2006, no change from 2005.

New immigrants to Canada are more than twice as likely to be in low income as the Canadian born, a gap that has been widening for two decades.

Slightly over one in ten (12%) immigrants (excluding youth and children less than 16) were living in low income in 2006.

More than one-half (52%) of recent immigrants with a university degree worked in a job requiring only high school education at some point during the six-year period. This was almost twice the proportion of 28% among their Canadian-born counterparts.

How do I find survey results?

As soon as data from a particular year of SLID have been processed, the survey results are announced in The Daily, Statistics Canada's official release bulletin. Information for the 2006 reference year was released in May 2008.
