To expand on this a little, the 2019 tracts are largely similar to 2010 tracts (and 2020 tracts are completely different). There are changes, particularly early in the decade (and particularly in areas of upstate New York, Los Angeles, and Arizona), but the vast majority of tracts are largely unchanged, making it easy to make data comparisons across the decade (eg. comparing 2015-2019 data to 2010-2014).
