# Women in the labor force by age of children in Montana

Select Table Type:

- Detailed
- Sort / Rank

**Definitions:**
This indicator represents the total number of women ages 20 to 64 who are in the labor force and have children ages 0 through 17, by age of children. The labor force is defined as persons who are employed (part-time or full-time) or unemployed (not working, but actively looking and available to accept a job).

Women with children ages 0 through 5 include women who may also have older children less than 18 years. Women with children ages 6 through 17 include women who only have children in this age group (i.e., no children ages 0 through 5). Thus, these two categories are mutually exclusive and will sum to the total number of working women with children.

The denominator for the percentages is all mothers with children by each respective age group, in respective geographic areas.

NA - Estimates are suppressed when unreliable or the relative standard error is greater than 30%.

GEOGRAPHY - Data reflect the mother’s place of residence.

DATE - The ACS data reflect a 5-year pooled estimate. That is, the estimate is the result of data being continuously collected nearly every day for five years.

LIMITATIONS - Characteristics for geographic areas experiencing dynamic change due to things such as an environmental catastrophe (e.g., flood) or a plant closing will be mitigated since these estimates cover five calendar years of data. Caution is needed when using the multiyear estimates for estimating year-to-year change in a particular characteristic. This is because four of the five years in the 5-year estimate overlap with the next year’s estimate. Ideally, trend analysis with multiyear estimates should be done using estimates from non-overlapping periods (i.e., 2006-2010 and 2011-2015).

Data are based on a sample and are subject to sampling variability. The degree of uncertainty for an estimate arising from sampling variability is represented here through the use of a margin of error. The value shown here is the 90 percent margin of error. The margin of error can be interpreted roughly as providing a 90 percent probability that the interval defined by the estimate plus or minus the margin of error (the lower and upper confidence bounds) contains the true value. The larger the margin of error, the less confidence one should have that the reported results are close to the true value. Use caution when drawing conclusions based on small numbers, as smaller samples yield larger margins of error. Margins of error corresponding to a 90 percent confidence interval for each estimate can be found at Women in the labor force by age of children.
