In 1939, approximately 1,300,000 people resided in Warsaw; by 1945 the population had dropped to 420,000. During the first years after the war, the population growth rate was high and the city soon began to suffer from the lack of flats and dwellings to house new incomers. The first remedial measure was the enlargement of Warsaw's total area (1951) – however the city authorities were still forced to introduce limitations; only the spouses and children of permanent residents as well as some persons of public importance (renowned specialists, artists, engineers) were permitted to stay. This negatively affected the image of an average Warsaw citizen, who was perceived as more privileged than those migrating from rural areas, towns or other cities. While all restrictions on residency registration were scrapped in 1990, the negative opinion of Varsovians in some form continues to this day.
