The story becomes more complicated when examining *where* homes were added in each metro area, though! Liberal metropolitan areas like NYC & Seattle added many more homes near existing homes than did most conservative metro areas. That means their residents experienced more nearby construction.

When I examined trends among cities, I found that cities with more conservative residents added housing much more quickly... *But* more liberal cities added much more housing in infill areas. Liberal cities did a better job adding homes through construction in existing neighborhoods.

My findings reaffirm that liberal places are doing a poor job adding homes. BUT they also show that conservative places are doing a poor job adding homes other than on greenfields—as in, outside existing neighborhoods. Journal article: www.tandfonline.com/doi/full/10.... Free pre-print version ⏬
