Romania is moving, one commune at a time

The city and its ring

The city stands still. The commune next to it grows

For the country's 13 largest cities, we compared the city's average net migration rate with the average of the communes directly bordering it, across two windows: 1995–2004 and 2015–2024. Two decades ago the gap was barely visible. Today, with the exception of Bucharest and Iași, the big cities lose net population or stagnate, while the communes around them grow by tens per thousand a year — a suburbanisation pattern that has intensified, not eased.

The overnight jumps

The localities where population exploded in a single year

Among the largest single-year jumps in net migration rate across the whole series, four names recur, all from three counties bordering the Republic of Moldova — Iași, Botoșani, Vaslui. It is not a coincidence of geography, and the pattern repeats: a sharp rise over 2–4 years, then an equally sharp correction in the opposite direction.

The net rate is per thousand residents; "people" is the raw difference between arrivals and departures that year. Localities under 150 residents are excluded, so that statistical noise does not dominate the ranking.

A methodological story

Sometimes the population map is the map of a law, not of housing

Moșna and Grajduri (Iași) nearly triple their registered population in 2014–2016. Scânteia (Iași) doubles, then triples, between 2016 and 2022. Ripiceni (Botoșani) doubles its population in 2016–2018. Bogdana and Ferești (Vaslui) do the same in 2023–2025 — the most recent wave, still under way. In each case the growth does not come from births: it is registered arrivals, mostly representing people changing their home address from abroad directly into that commune.

INS explicitly warns, in the methodology of its locality-level population matrix (POP107D), that some demographic jumps — including at Ripiceni and Scânteia, named directly — were influenced by the immigration of people born in the Republic of Moldova. The most plausible mechanism: Moldovan citizens who reacquire Romanian citizenship must, at some point in the procedure, declare a home address in Romania; a handful of small communes, often with relatives or acquaintances willing to host the address, became successive hubs of mass registration. The wave in Scânteia and Ripiceni corrected itself in 2023–2025, with strongly negative net rates — the same people, or others, dropping off the register. Bogdana and Ferești show exactly the start of the same cycle.

This is not an isolated hypothesis: the same two counties, Iași and Vaslui, show up independently flagged in another INS dataset — births by locality — with a birth-count bump over the same years, for the same structural reason. The map on this page is, then, partly a map of a legal incentive: whoever needs a Romanian home address finds one more easily in a small commune than in a big city, and a few small communes experienced that as a sudden demographic explosion, followed by an equally sudden reversal.

The overall picture

For most localities, migration barely moves the needle

The distribution of the cumulative net rate (1992–2025, set against 2025 population) for the 3,153 localities with more than 500 residents shows a central mass close to zero and long tails in both directions — suburban magnets to the right, isolated communes to the left.
