Sources, population, and key definitions

Sources

Two data sources have been used in this analysis, Statistics New Zealand's Household Labour Force Survey (HLFS) and the Survey of Working Life (SoWL). Annual average data from the HLFS has been used to help remove any seasonal factors in the data. The SoWL was a supplement to the HLFS in the March 2008 and December 2012 quarters. Data from the December 2012 quarter SoWL has been used in this analysis.

Both data sources used are, by definition, restricted to only identifying relationships within a household. This poses some limitations[1] on the data, such as when dependent children live with another parent in a different household, or where the mother's partner lives in a separate household. The HLFS would not identify these relationships (as they are outside the bounds of the physical household), but they may still affect mothers' engagement with the labour market.

Population

The population used for this paper is women aged 25–49 years. This age group captures the majority of mothers of dependent children and removes some of the significant age effects associated with the younger and older age groups that make comparisons between 'mothers' and 'non-mothers' difficult. Restricting the population by age is a commonly used practice when researching mothers (eg Misra, Budig, & Boeckmann, 2011; OECD, 2011).

Key definitions

Dependent child: A child in the household, aged 17 or under, who is not in full-time employment (if aged 15 or over).

Mother: A woman in a parent role to at least one dependent child, living in the same household as the child/ren.

Partner: A person in a relationship with another person residing in the same household, regardless of marital status.

Employment rate: The number of people employed divided by the working-age population

Labour force participation rate: The number of people in the labour force (the employed plus the unemployed) divided by the working-age population.

Unemployment rate: The number of people unemployed (actively seeking and available for work) divided by the labour force.
