Estimated Population of Young Adults in the US With a Parent Who Has Ever Spent Time in Jail or Prison
"The prevalence of any PI [Parental Incarceration] was 12.5% with the 95% confidence interval (CI) of 11.3% to 13.8%. The distribution of incarceration status by category was: neither parent (87.5%, 95% CI: 86.2%–88.7%), father only (9.9%, 95% CI: 8.9%–10.9%), mother only (1.7%, 95% CI: 1.4%–2.0%), and both parents (0.9%, 95% CI: 0.7%–1.2%). A significant association was found between race and PI. Black and Hispanic individuals had the highest prevalence of PI, 20.6% and 14.8%, compared with 11.9% for white individuals and 11.6% for those classified as other. Pairwise comparison indicated the black and white prevalence rates were significantly different."
Note: Regarding study sample size: "The current study used data from the National Longitudinal Study of Adolescent Health (Add Health), a 4-wave longitudinal study following a nationally representative probability sample of adolescents in grades 7 through 12 in the 1994–1995 school year.46 The first 3 waves of Add
Health data were collected from April to December 1995, from April to August 1996, and from August 2001 to April 2002. The fourth wave of data was collected in 2007 and 2008. The full sample for Wave 4 included 15 701 or 80.3% of the eligible participants from Wave 1. The response rates for Waves 1, 2, 3, and 4 were 79.0%, 88.6%, 77.4%, and 80.3%, respectively. The mean ages of participants during the 4 waves of data collection were 15.7 years, 16.2 years, 22.0 years, and 28.8 years, respectively.
"The current study was based on 14,800 participants who were interviewed during Wave 1 and Wave 4 and have a sampling weight. Of the 15,701 participants who participated in both Wave 1 and Wave 4 interviews, 14,800 participants have a sampling weight at Wave 4 interview that could be used to compute population estimates. For data analysis, data describing participants’ sociodemographic characteristics from Wave 1 of the Add Health study were combined with Wave 4 self-reported health outcomes and PI history."
