into 10 inner urban and 11 suburban districts. The centre is formed by the district Altstadt (old town) and the Gründerzeit districts Nordvorstadt in the north, Parkvorstadt in the east and Westvorstadt in the south and west. Later additions are Südstadt in the south and Schönblick in the southwest. Finally, there are the Plattenbau settlements, constructed during the GDR period, Weststadt and Nordstadt as well as two industrial areas in the north and west. The 11 suburban districts are villages which became incorporated during the 20th century; however, they have mostly stayed rural to date: Gaberndorf (incorporated in 1994) Gelmeroda (1994) Legefeld/Holzdorf (1994) Niedergrunstedt (1994) Oberweimar/Ehringsdorf (1922) Possendorf (1994) Schöndorf (1939) Süßenborn (1994) Taubach (1994) Tiefurt (1922) Tröbsdorf (1994) Demographics Over the centuries, Weimar remained a small town of less than 5,000 inhabitants. When it became the capital of Saxe-Weimar in 1572, population growth was stimulated and population increased from 3,000 in 1650 to 6,000 in 1750. Around the year 1800, Weimar had 7,000 inhabitants. Their number grew constantly over the years to 13,000 in 1850, 28,000 in 1900 and 35,000 at the beginning of World War I. During the interwar period, the new capital of Thuringia saw a population boom, which led to 65,000 inhabitants in 1940. Since that time, the population levels have stagnated. The years 2009 to 2012 brought a moderate growth of approximately 0.35% p. a., whereas the population in bordering rural regions is shrinking with accelerating tendency. Suburbanization played only a small role in Weimar. It occurred after the reunification for a short time in the 1990s, but most of the suburban areas were situated within the administrative city borders. The birth surplus was +3 in 2012, this is +0.0 per 1,000 inhabitants (Thuringian average: −4.5; national average: −2.4). The net migration rate was +4.5 per 1,000 inhabitants in 2012 (Thuringian average: -0.8; national average: +4.6). The most important regions of origin are rural areas of Thuringia, Saxony-Anhalt and Saxony as well as foreign countries like Poland, Russia, Ukraine, Hungary, Serbia, Romania and Bulgaria. Like other eastern German cities, Weimar has a relatively small foreign population (compared to the German average): circa 4.0% are non-Germans by citizenship, while 7.9% have a migrant background (according to 2011 EU census). Differing from the national average, the biggest groups of migrants in Weimar are Vietnamese people, Russians and Ukrainians. During recent years, the economic situation of the city
