12.1.2 Race/Hispanic origin

We see that only RIDRETH1 is available in both 2017-2018 and 1999-2000:

RACE_TBL <- DEMO %>%

12.1.3 US Armed Forces

We see that only DMQMILIZ is available since 2011-2012, prior to 2011, the veteran status information (released in the variable DMQMILIT in the demographics file in 1999-2010)

12.1.4 Country of Birth

Due to the concerns of disclosure risk, starting in 2011, country of birth was recoded into two categories: 1) Born in 50 U.S. states or Washington, DC; and 2) Born in other countries, including U.S. territories.
