How many structures are in the 2022 NSI dataset?

Was looking around at different nationwide buildings datasets. Curious about NSI's count.

• USA structures: 131,811,972

NSI is built based on a variety of inputs including both Bing Footprints and USA Structures footprints. There is no perfect dataset out there, but rather various datasets that fill needs at different qualities. In the NSI you can look at the field ftprntsrc that identifies which footprint dataset was used to place the point.

I will get a count of the national dataset and post it.
