(3) Mother's Employment Status

The rate of employed mothers increased year by year.

The rate of mothers with or looking for a job is higher with children without younger siblings.

The rate of employed mothers has increased year by year, from 25.1% in the 1st survey to 41.8% in the 4th survey (Figure 2).

The rate of mothers newly employed during the past year (answering "unemployed" in the 3rd survey and "employed" in the 4th survey) was 16.4%. The rate is lower with children who have younger siblings (12.6%), than without (18.5%). The rate in the 3rd survey of unemployed mothers who replied, "seeking a job" in the 4th survey, was also lower with children who have younger siblings (8.3%) than without (13.5%) (Table 4).
