I’m sorry, Catherine. Various other demands keep delaying the tract-to-tract crosswalk release. It’s in the mix for things I hope to get done this spring, but there remain some other more pressing things that may still push it out farther.
In the meantime, with an extra step (and some much larger files), you could use the NHGIS block-to-block crosswalks to standardize data from tracts–or to create your own tract-to-tract crosswalks–following the instructions I provided in this post. There I describe how to use block-to-block crosswalks to standardize data from block groups–which is no longer necessary now that we’ve released block group crosswalks. But the instructions apply the same to tracts if you just replace “block group” with “tract”.
