due to the advances of the city's economy from the increase of tourism, and the boom of innovative tech companies, the rent increased by more than 50 percent by the 1990s. many affluent tech workers migrated to san francisco due job opportunities and lack of housing in the south bay. until the end of the 1960s, san francisco had affordable housing, which allowed people from many different backgrounds to settle down, but the economic shift impacted the city's demographics. all of this resulted in constant gentrification of many neighborhoods. residents of areas such as the tenderloin and the mission district, which house many immigrants and low-income families, are faced with the possibility of eviction, in order to develop low-income housing to more luxurious housing, which caters to the advances of the economy. for example, residents of the mission district experienced 14.2 percent of the citywide evictions in the year 2000.
