This document explains the files necessary for replication analyses of 'Age-Heterogamous Partnerships: Prevalence and Partner Differences by Marital Status and Gender Composition.' 

The three Stata .do files create the analytic dataset (.do file 1/3), create and code most necessary variables (.do file 2/3), and run analyses (.do file 3/3). 

The two .csv files (figure2 and figures3_5) contain estimates produced from Stata analyses. They are imported into R. The R script figure_script.R creates and saves the figures. 

Please note that users will need to fill in the appropriate file pathways where noted in the .do file and R script, since doing so sets the working directory (computer folder) to import data and/or save figures. 

All estimates were run using Stata/SE 18.0, and figures 2-5 were produced in R Studio version 2023.09.1 with the ggplot2 visualization package. Figure 1 was produced with Stata. 

Data File Description

The five-year 2017-2021 American Community Survey (ACS) data file was downloaded from IPUMS-USA: https://usa.ipums.org/usa/. Users can create an account and download the data for free. 

The IPUMS website allows users to download five-year data files and to select what variables to include. 

The data extract contained the following variables:

Most of these variables were not used in the final analysis, but all ACS variables the paper analyzed are present in the above list. Please see the Stata .do files for more information.
