I'm working on R, trying to get Census data such as Total households, marriages (same/opposite sex), etc. I noticed some of the variable IDs changes depending on the year. I can't find anywhere the reason behind it or how to navigate through this "issue". So far finding the variable ID for the different types of marriages/cohabiting has been the most challenging. Does any ones has any suggestions?
For example: Using ACS1,Year 2019 for Married Couple Households, Opposite-sex the variableID is B11009_003, but not the same for the years before (2018, 2017, 2016, etc..). Any suggestions how to find the variable ID for the years before 2019?
Take a look at the table shells file for each year, available here: https://www.census.gov/programs-surveys/acs/technical-documentation/table-shells.html
This page on new, changed, and deleted tables discusses the extensive changes made to B11009: https://www.census.gov/programs-surveys/acs/technical-documentation/table-and-geography-changes/2019/5-year.html
Thank you, Bernie! I've been looking for this type of info. maybe I'm not using the correct keywords
