This register did not include women, orphans, Christians below the age of puberty, high-ranking officials, and the mentally or physically incapacitated, so the actual population would be much higher.

On 19 February 1968, an earthquake (7.1 on the Richter scale) demolished most of the houses,[7] which were replaced by concrete prefabricated buildings laid out in a military-like camp formation.

Nonetheless, the island retains a very attractive capital, also called Agios Efstratios, while preserving a rather unspoiled Mediterranean environment with pristine beaches.

Athens News Agency[8] reported that, on 4 June 2009, at a two-day international conference in Athens on "Climate change and Challenges for the Future Generations"[9] under the patronage of UNESCO, Greece's Development Minister Kostis Hatzidakis said that Agios Efstratios would soon become the country's first "green" island, entirely powered by renewable energy sources (RES), its residents relying on solar and wind generated energy and moving around the island on bicycles and in electric cars.

Agios Efstratios has one port, which offers year-round ferry connections to the island of Lemnos, as well to mainland Greece, namely Lavrio.

There is also a small heliport on the main village outskirts, but it is used mostly for emergency airlift, or coast guard and military helicopters' stopover.

In the game, Stratis is mostly composed of sparse military installations and a small airfield, with most of the civilian settlements on the island having been left abandoned following a civil war.
