Whether a young person is in school or working is an indicator of future success. Reasons for youth not being in the workforce or enrolled in school vary significantly, but one common factor is the level of literacy and math skills developed in school. The U.S. has a larger share of disengaged youth and individuals with low numeracy skills than other developed nations. Young people not in school or working are more likely to engage in risky behaviors such as drug use and violence.

In 2018-22, 5% of Westchester County youth were neither working nor in school, lower than the state and nation (both 7%) and lower than 2008-12, when the rate was 7%. The state and national rates both declined by about a point since 2008-12. Westchester County's rate (5%) was similar to the surrounding counties of Rockland (6%), Nassau (5%) and Putnam (4%).

The multiyear figures are from the Census Bureau's American Community Survey. The bureau combined five years of responses to the survey to provide estimates for smaller geographic areas and increase the precision of its estimates. However, because the information came from a survey, the samples responding to the survey were not always large enough to produce reliable results, especially in small geographic areas. CGR has noted on data tables the estimates with relatively large margins of error. Estimates with three asterisks have the largest margins, plus or minus 50% or more of the estimate. Two asterisks mean plus or minus 35%-50%, and one asterisk means plus or minus 20%-35%. For all estimates, the confidence level is 90%, meaning there is 90% probability the true value (if the whole population were surveyed) would be within the margin of error (or confidence interval). The survey provides data on characteristics of the population that used to be collected only during the decennial census. Data for this indicator are released annually in December.
