The registry is overwhelmingly local government by count, and that is a fact about what the registry is rather than a caveat hidden at the bottom of a page. Local-level institutions are 678,242 of 719,588 records (94.25% of everything in it). Any statistic computed over the registry as a whole is, to a first approximation, a statistic about local government. A reader interested in national ministries is working with 6,360 records, and should weight, filter, or stratify accordingly rather than treating the registry as a balanced sample of government.

Within that local tier, two distinct kinds of institution should not be run together. Municipalities (cities, towns, and communes) account for 664,901 records, or 92.40% of the registry. US school districts account for a further 13,341, or 1.85%. Together they make the 678,242 local-level total. “Local” and “municipality” are therefore not interchangeable on this page or in any analysis drawn from it: school districts are special-purpose authorities with a single policy remit, they exist in one country, and folding them into a municipality count would misstate both.

The long tail of that table is the cross-country layer: twenty-odd institution types, each with somewhere between thirty and a few hundred members worldwide, one row per country that has such a body. Those categories are small by construction rather than by omission: there are only so many central banks.
