More accurately described as "where people were located since 2,300 BCE that were capable of recording meteor strikes and recorded them in a form that survived until present day and made its way into a database of meteor strikes." Latitudinal variations in the density of meteor strikes wouldn't surprise me; longitudinal ones should be entirely explained by the observational effect. Hence we see a ton of meteor strikes in the continental US and virtually none in rural China, though both are on similar latitudes.

What's the data source? If it's the US meteorical society database, then it probably includes "finds" in additional to witnessed "falls".
