Countryaah data, Hungary has a population density of 107 residents per km
2 with the largest population concentrations in
the Budapest, Miskolc and Szeged areas. Through the
post-World War I borders, Hungary became a relatively
homogeneous state; the ethnic Hungarians make up 90-95
percent of the population. The largest minority group is the
Roma, which is estimated to be 4–6 percent; other groups are
Germans (2 percent) and Slovaks (1 percent).
Hungary has for a long time had a negative natural
population change. The proportion of residents in cities is
71 percent. The largest cities are Budapest (1.8 million
residents, 2017), Debrecen (202,000) and Miskolc (157,200).
Due to Hungary's large post-World War II country
resettlement, Hungarian is the dominant language in the
country. Among minority languages, primarily Romani. Smaller
groups speak Romanian and German.
Christianity reached present-day Hungary already during
Roman times. During the 9th century, missions from both
Byzantine and German existed. When Hungary transitioned to
Christianity under Stefan I (about the year 1000), they
joined the Latin Western Church. The Archbishop's seat
became Esztergom. Through the Reformation a Lutheran and a
Reformed Church arose. In 1988, 66% of Roman Catholics, 18%
of Reformed, 4% of Lutherans and all other communities were
counted 2.4%. During the communist era, the religious
communities were strongly oppressed. In 1990 freedom of
religion was introduced. Seized property was returned to the
communities during the 1990s. The number of Roman Catholic
orders is steadily increasing.
