history of the district, see District sections; for the 1938 detached parts of the district, see: Penzing. Population Population development In 1869, the current area of the Hietzing District included only 9,808 inhabitants. Due to the low population density at that time, Hietzing was one of the few districts which had a persistent population growth. Before the start of the First World War, the population in 1910, with 34,883 inhabitants, had more than tripled, but then the growth slowed down. In 1971, the district reached 57,068 people, the highest population to date. Then the population stagnated, falling 4% during the next 2 decades, and later dropping another 10% in the 1990s, but rose gradually after the millennium year. From 2001, the population in Vienna citywide trended to grow, including in Hietzing. At the beginning of 2007, the population stood at 51,120 people. Population structure The average age of Hietzinger population in 2001 was significantly higher than the average in Vienna. Fundamentals are the high density of pensioners-houses, a large nursing home in Lainz (Geriatriezentrum at Wienerwald) and a very small proportion of foreigners. The number of children under 15 years stood at 13.0%, as only slightly below the Vienna average of 14.7%. The proportion of the population from 15 to 59 years, however, with 56.8% (Vienna: 63.6%), was strongly below average. The proportion of people aged 60 years or more in 2001 was 30.2% (Vienna: 21.7%), the highest of the whole of Vienna. Due to the high proportion of older people in 2001, the proportion of women in Hietzing was the largest in Vienna: 44.3% men, 55.7% were women. The number of Hietzing married had a share of 42.8%, compared with Vienna citywide 41.2%, so slightly above the average of Vienna [6]. Origin and language The proportion of foreign district residents in 2005 was 10.4% (Vienna citywide: 18.7%) and has over 2001 (7.9%) in Vienna as strong rising trend. The highest proportion of foreigners in 2005 represented approximately 2.1% share of the district population of nationals from Germany. Hietzing was next to the inner city as the district with the highest German foreign residents. Another 1.4% were citizens of Serbia and Montenegro, 0.7% were Polish, 0.5% Turkish, and 0.4% Slovak citizens. In 2001, a total of 16.3% of the population of the Hietzing District was not born in Austria. Nearly 1.9% expressed as a language Serbian, 0.5% Turkish, and 1.0%
