I'm sure most people in this group are power users, and well versed in Census concepts -- however, I'm posting this anyway. I'll be presenting a national webinar session on June 26th, 2025 at 2pm ET on "smaller" Census geographies. The presentation is titled "Good Data Come in Small Geographies". I'll go through Blocks, Block Groups,Tracts and ZCTAs and explain some of the data limitations and advantages of each. If you have any questions about the webinar, you are welcome to reach out to me directly: david.j.kraiker@census.gov
