Hi There! I am a researcher/cartographer at Michigan State University and IDV Solutions. I came across the excellent post about mapping secondary homes at the county level and am quite impressed -it tells an excellent story. I’ve scoured the American Community Survey and havn’t been able to find the data used to make these maps. Is there any way someone on your team could share that data with me directly? Thanks in advance for any help!
Cheers,
John Nelson
