I seek New Mexico county-level data for: 2021 ACS 5-Year Estimates Subject Table S0102: POPULATION 60 YEARS AND OVER IN THE UNITED STATES. However, for 49% (16/33) counties, the data are missing. Is there an explanation?
There is an errata note specifically about Rio Arriba County, NM. Lots of data missing (and holes in my nationwide maps over the years). It it not an error on your part.

Meant to add the topics affected: income and earnings, kitchen and plumbing facilities (vacant units only), labor force and employment, migration, and poverty.
