About this ranking

Annual number of new privately owned housing units authorized by building permits, from the US Census Bureau Building Permits Survey.

Final annual county estimates include imputation for missing reports. Counts housing units, not buildings, starts, completions or sales. Covers permit-issuing areas; areas where permits are not required are outside the survey. Not seasonally adjusted or expressed as an annualized monthly rate. The total is the sum of units in the four published structure categories; inputs are retained.

Every value in the ranking comes from the same publisher and the same period, so the counties are compared on one definition. Equal values share a rank.
