The following data are now available to Add Health contract researchers.
Wave I State Demographic Characteristics, Exclusionary Indices, and Inclusionary Indices
These data provide measures of punishment regime variation in state-based policies, practices, and programs, both in their punitive and non-punitive forms and some additional state demographic control variables. These data were gathered to use with Add Health for multilevel analyses. N=20,745.
Contextual Wave IV Database
The data provide an important update to the contextual variables already available in Wave IV by including information at the state- and county levels. Additionally, there are a few new variables in the present database that are absent from other waves. N=15,701.
Contextual Wave V Database
This contextual database further expands the extensive contextual data currently available to users of the National Longitudinal Study of Adolescent to Adult Health (Add Health) through the provision of numerous measures reported by the U.S. Census Bureau’s American Community Survey (ACS), rural-urban commuting area codes, U.S. Climate Atlas, and Uniform Crime Report. N=12,300.
Wave V County Health and Mobility Data Documentation
The Wave V County Health and Mobility database summarize the socioeconomic, health, and mobility characteristics of the environments in which Add Health participants were living at the time of their Wave V interview. County-level data describe (1) levels of and trends in chronic disease (hypertension, type-2 diabetes) and health risk behaviors (obesity, smoking, alcohol use); and (2) economic opportunity and inequality. N=12,300.
Wave V – ACA Medicaid Expansion Data
This data file provides the year in which states expanded Medicaid under the Affordable Care Act. These dates are attached to the location in which Add Health participants were living at Wave V. N=2,300.
Waves I, IV, and V – The Opportunity Atlas: Mapping the Childhood Roots of Social Mobility Data
This file enhances the existing Add Health contextual database through the addition of measures essential to understanding the determinants and sequelae of socioeconomic mobility. Specifically, it aims to characterize the socioeconomic mobility of Add Health participants at Wave I, IV, and V. WI N=20,745, WIV N=15,701, WV N=12,300.
Wave IV City Crime Rate Data
This Crime Rate Data file facilitates research examining the impact of community violence on the health trajectories of Wave IV Add Health participants by providing police department crime data from 13 U.S. cities with high crime rates. N=15,701.
Wave V City Crime Rate Data
This Crime Rate Data file facilitates research examining the impact of community violence on the health trajectories of Wave V Add Health participants by providing police department crime data from 13 U.S. cities with high crime rates. N=12,300.
