“no data” = no evidence rows for that axis — 24 of 428 metros in scope lack GDP-growth evidence; 16 lack permit evidence. Absent values are never imputed or shown as zero; a metro is excluded only when you filter on an axis it has no value for.
GDP growth vs same-country national benchmark: Statistics Canada + U.S. BEA / OMB Census (OMB July 2023; stored StatCan series through 2022; periods 2020-2022, 2020-2024). Residential-permit growth: Statistics Canada + U.S. Census Bureau BPS / OMB Census (OMB July 2023; table 34-10-0292 through 2025; periods 2021-2025). Nominal growth includes price changes; US and Canada levels are not compared across currencies. GDP growth is each metro's CAGR vs its own country's national benchmark over that country's stored period (CA 2020-2022 · US 2020-2024); US evidence is BEA nominal GDP in USD, Canadian CMA evidence is Statistics Canada GDP at basic prices in CAD. Growth rates may be compared across countries only with that basis and period difference disclosed. GDP levels are not part of this screen and are never ranked across countries. Rows open the decision-evidence analysis at /places/decision. Delineation: US CBSA (OMB July 2023) + Canada CMA.
