Meeting summary<br> 
Quick recap<br> 
The meeting focused on the recent release of Census Bureau's CB Gen2025 shapefiles and related demographic data updates. Warren presented the new data structure, which includes updated block groups, county subdivisions, and school districts across states, explaining the differences between Tiger line files and the newer CB versions, which are trimmed to shorelines and have linearized boundary points for faster display. The group discussed upcoming data releases including 2025 annual building permits, school system funding data, and vintage 2025 population and housing information. Warren also demonstrated updates to the Community Resilience Project map, which now uses consistent color schemes for both county and track-level data, and showed new congressional district boundary changes in Virginia. Finally, Warren presented a new Columbia, Missouri-focused project using current Tiger and CB shapefiles, which he plans to share with local contacts and potentially expand to other areas for a fee of $1,000-$2,000 per custom project.
<br> Next steps
<br> -	Warren: Check on updating the BLS data (specifically the missing DD file) by next week.
<br> -	Dan: Send Warren the colorblind-friendly (Savitus/CIBI DIS) color palette for use in mapping.
<br> -	Warren: Send the new Columbia/Boone County mapping project to Ann, Dennis, and Dan for review and feedback.
<br> -	Warren: Consider making improvements to the community resilience map's interpretation and possibly update it next week.
<br> -	Warren: Review and potentially expand the Columbia project with additional geography and subject matter, as appropriate, before wider distribution.
<br> -	Warren: Send follow-up email to Ann, Dennis, and Dan regarding the Columbia project for their opinions.
<br> Summary
<br> Census CB Generalized Shapefiles
<br> Warren presented an overview of the recently released Census Bureau CB Gen Z 2025 shapefiles, explaining their organization by state and geography type. He detailed the differences between these files and the Tiger line files, highlighting that CB files are trimmed at shorelines and have linearized points for faster display. Warren also discussed the process of sourcing data from individual counties and noted that while these files are current, they may not align perfectly with upcoming ACS 2025 data expected in December.
<br> Census Data Release Updates
<br> Warren explained the process of extracting and using shapefiles, including the advantages of standardized data across different files. He outlined upcoming Census data releases, including the 2025 annual building permits data, city and town population data, and housing units data, emphasizing the differences between annual and monthly data releases. Warren also mentioned the release of the 2024 School System Sources and Users of Funds data and discussed the vintage 2025 data releases, including details on population and housing data.
BLS Data and Mapping Updates
<br> Warren discussed updates on BLS data and the Community Resilience Project, mentioning plans to consolidate missing files by next week. He demonstrated changes to the interactive mapping system, which now uses a unified color legend for comparing track and county-level data. Dan offered to share a colorblind-friendly palette for the maps, and Dennis inquired about the correlation between the percentages in the social vulnerability index and specific disaster types, to which Warren explained it measures 3 out of 5 components without specifying which ones.
<br> Resilience Mapping Project Discussion
<br> The group discussed Warren's mapping project showing resilience data at the track level, which Dan suggested would be most useful to real estate professionals and city planners due to its localized nature. They examined how congressional district boundaries in Virginia had changed, with Warren noting how the new VA8 district now includes much more rural territory compared to the previous version. Warren also presented a new Columbia, Missouri-focused project using TIGER data that could be replicated for other areas at a cost of $1,000-$2,000, with potential applications for real estate markets and political campaigns.
