Survey on Early Learning and Child Care Arrangements (SELCCA)

Detailed information for 2022

Status:

Active

Frequency:

Occasional

Record number:

5287

Statistics Canada is gathering information on early learning and child care arrangements for children under the age of 6 in Canada.

Data release - Scheduled for Spring 2022

Description

This survey is designed to collect information on the use (or non-use) of early learning and child care in Canada for children younger than 6 years old. It asks whether or not a particular child under the age of 6 in the family is enrolled in early learning and child care, and collects information about the different types of arrangements the child uses and their frequency of use, the cost of early learning and child care, the difficulties some families may face when looking for early learning and child care arrangements, and the reasons for not using it. The survey will also cover the COVID-19 pandemic and its impact on early learning and child care.

Subjects

  • Child care
  • Children and youth

Data sources and methodology

Target population

The target population is children across the 10 provinces of Canada who are less than 6 years old (as of February 28, 2022). Children living on reserves are excluded from the target population.

Instrument design

The content for the Survey on Early Learning and Child Care Arrangements electronic questionnaire was drafted in consultation with several external subject matter experts.

The questionnaire underwent cognitive testing in the form of in-depth interviews in both of Canada's official languages, conducted by Statistics Canada's Questionnaire Design Resource Centre. The goal of the qualitative study was to test the survey content.

Sampling

This is a sample survey.

Sampling unit:
This is a targeted respondent survey. The sampling unit is the person knowledgeable about the child care arrangements for a child who lives in their household and is less than 6 years of age.

Stratification method:
The frame for the Survey on Early Learning and Child Care Arrangements was stratified by province and a simple random sample was selected independently within each province.

Sampling and sub-sampling:
Sufficient sample was allocated to each of the provinces so that the survey could produce provincial level estimates. An initial sample of 20,000 targeted respondents was selected and sent to collection. The selection of a sample unit is done in two stages. First, a simple random sample of CCB recipients is selected. The second stage consists of selecting randomly, for each recipient selected, a child among the recipient's eligible children. A child is eligible if he or she is less than 6 years old.

Data sources

Data collection for this reference period: 2022-01-24 to 2022-02-18

Responding to this survey is voluntary.

Data are collected directly from survey respondents either through an electronic questionnaire (EQ) or through CATI (computer assisted telephone interviewing).

Error detection

Electronic files containing the daily transmissions of completed respondent survey records were combined to create the "raw" survey file. Before further processing, verification was performed to identify and eliminate potential duplicate records and to drop non-response and out-of-scope records.

In addition, some out-of-scope respondent records were found during the data clean-up stage. All respondent records that were determined to be out-of-scope and those records that contained no data were removed from the data file.

After the verification stage, editing was performed to identify errors and modify affected data at the individual variable level. The first editing step was to identify errors and determine which items from the survey output needed to be kept on the survey master file. Subsequent to this, invalid characters were deleted and the remaining data items were formatted appropriately.

Imputation

For a small number of cases, either the province of residence or the date of birth of the selected child were not stated in the submitted questionnaires. In that situation, the missing values were imputed with the province or date of birth from the sample file.

Estimation

The estimation of population characteristics from a sample survey is based on the premise that each person in the sample represents a certain number of other persons in addition to themselves. This number is referred to as the survey weight. The process of computing survey weights for each survey respondent involves several steps.

1) Each selected respondent is given an initial weight equal to the inverse of its selection probability from the sampling frame (Canadian Child benefit file, CCB). Respondents identified as out-of-scope during collection are dropped from the sample.

2) The respondents' weights are then adjusted to take into account non-response based on the province, number of children and household income (estimated from the CCB file).

3) The person (child) weights are obtained by multiplying each respondent's weight by the number of in-scope children for which the respondent receives a benefit according to the CCB file.

The person weights are calibrated by province and by age 0, 1, 2, 3, 4 and 5 separately. The counts used were the Labour Force Survey demographic counts.

Variance estimation is based on a re-sampling method called bootstrap estimation.

The Generalized Estimation System from Statistics Canada (G-Est) was used to generate the survey weights and bootstrap weights.

Quality evaluation

While rigorous quality assurance mechanisms are applied at all stages of the statistical process, the validation and detailed review of data by statisticians is the ultimate verification of quality prior to release. Many validation measures were implemented, they include:

a. Verification of estimates through cross-tabulations
b. Consultation with stakeholders internal to Statistics Canada
c. Consultation with external stakeholders

Disclosure control

Statistics Canada is prohibited by law from releasing any information it collects that could identify any person, business, or organization, unless consent has been given by the respondent or as permitted by the Statistics Act. Various confidentiality rules are applied to all data that are released or published to prevent the publication or disclosure of any information deemed confidential. If necessary, data are suppressed to prevent direct or residual disclosure of identifiable data.

Revisions and seasonal adjustment

This methodology type does not apply to this statistical program.

Data accuracy

Survey errors come from a variety of different sources. One dimension of survey error is sampling error. Sampling error is defined as the error that arises because an estimate is based on a sample rather than the entire population. Sampling error can be expressed through a confidence interval (CI) or coefficient of variation (CV).


Non sampling error
The first type of errors treated were errors in questionnaire flow. For skips based on answered questions, all skipped questions were set to "Valid skip" (6, 96, 996, etc.). For skips based on "Non-response", all skipped questions were set to "Not stated" (9, 99, 999, etc.). The remaining empty items were filled with a numeric value (9, 99, 999, etc., depending on variable length). These codes are reserved for processing purposes and mean that the item was "Not stated".

Non-response bias
The survey estimates are adjusted to account for non-response through the survey weights. To the extent that the non-responding persons differ from the rest of the sample, the results may be biased.

Coverage error
Coverage errors arise when there are differences between the target population and the observed population. The target respondent is the person knowledgeable (aged 15 years and older) about the child care arrangements for a child who lives in the household and is less than 6 years old. The survey frame is the Canada Child Benefit (CCB) file and it contains every parent who is registered to receive a benefit. It is estimated that the frame represents 96% of the children population of all ages. To the extent that the excluded population differs from the rest of the target population, the results may be biased. Note that the children born between October 25, 2021 and February 28, 2022 are not covered by the survey frame.
