What it means

The figure is the county's resident population on 1 January: the people whose usual residence is here, whatever their citizenship, not those whose identity document gives this address. The same measure as the national one, but published by county only from 2012.

The resident population is not counted but estimated — from administrative sources, from data received from other states' statistical institutes and from the census. That is why INS recomputes years already published, and why a year's figure may differ from what you saw last year.

The 42 counties add up exactly to the national total, and the site checks that at every import. The Municipality of Bucharest appears in the list at county level because that is how INS publishes it, although it is not a county.

By urban and rural

The same resident population, split by INS into the urban and the rural environment, on 1 January of each year. The two add up exactly to the figure above, in every published year.

By urban and rural The annual trend of By urban and rural, from 2012 to 2026, in people. Urban: a trecut de la 356,075 la 331,457. Rural: a trecut de la 416,904 la 450,491. The exact figures are in the table below. 300,000 350,000 400,000 450,000 500,000 maxim 373,551 331,457 450,491

The boundary between urban and rural is administrative, not statistical: Legea 351/2001 puts the municipalities and the towns in the urban half and the villages in the rural one. When a commune is declared a town, a few thousand people move from one line to the other without anybody having moved house, and over short spans that explains a change more often than a real migration does. The total changes in neither case.

The figure is the resident population on 1 January, the same measure as the national one. By county, however, INS publishes it only from 1 January 2012, although the national series begins in 2003. Some of the years in the series were recomputed by INS after their first publication; the value shown is already the corrected one, which is why it carries no marking.
