blockwts (DATA) population weights of Census blocks

Details

For documentation on EJSCREEN, see EJSCREEN documentation

blockwts is a table of all census blocks, with the weights reflecting what fraction of the parent blockgroup census 2020 population lived in that block. The weights are used to aggregate block-level data to blockgroup, for cases where only some of the blockgroup is in a circular buffer or polygon.

It also has a column called blockid that can join it to other block datasets.

For EJAM v3, AS/GU/MP/VI can appear in blockgroupstats, EJSCREEN export files, and map-facing blockgroup datasets, but this block helper file intentionally does not include Island Area blocks. Point-buffer/radius or block-weighted polygon analysis for AS/GU/MP/VI should return no-data results rather than block-weighted estimates.
