Most of the buses connecting Besnyő and Dunaújváros stop at the village, but the railway plays a more important role.

On April 3, 1952 the village (previously called Görögfalva, "Greeks' Village") took the name of Nikos Beloyannis, the Communist leader and resistance fighter, who had been executed 4 days earlier in Greece.

Starting in 1974, several Greeks left the village and went back to Greece, but many of them (especially the younger people) stayed in Hungary.

Now the majority of the population works in the nearby cities of Budapest, Százhalombatta and Dunaújváros.

According to the 2001 census it had 1,185 inhabitants, 23.4% of them considered themselves Greek, 61.4% Hungarian, 0,3% Romanian, 14,9% didn't answer.
