Social movements have played an important role in changing how cities develop. They help create policies and designs that meet the needs of different communities. Here are some key impacts:

1. Civil Rights Movement (1950s-1960s):

   • During this time, there were many changes in city policies to fight against racial segregation. For example, the Fair Housing Act of 1968 aimed to stop discrimination in housing. Because of this, more neighborhoods became mixed with people from different races. After 1960, the number of Black families owning homes increased from 41% to 46% by 1970.

2. Environmental Movement (1960s-1970s):

   • As people became more aware of environmental issues, important laws were passed like the Clean Air Act in 1970 and the National Environmental Policy Act in 1969. Now, city planning often includes Environmental Impact Assessments (EIA). These assessments are important for projects, such as building highways or public buildings, to understand their effect on the environment.

3. Women's Movement (1970s-present):

   • The viewpoints of women have become part of urban planning. This has led to safer public spaces being designed. Studies show that areas with more lighting and clear views have lower crime rates. This can make women feel safer by about 25%.

4. Affordable Housing Initiatives:

   • The demand for affordable housing has led to changes in city policies. A 2021 report by the National Low Income Housing Coalition said there is a shortage of 7 million affordable homes for very low-income renters. This shows the need for more advocacy and policy changes.

5. Community Gardening and Urban Agriculture:

   • The movement for urban farming supports local food production. In places like Detroit, the number of community gardens grew by 200% between 2008 and 2018. This not only helps people access healthier food but also brings communities together and revitalizes empty lots.

6. Gentrification Resistance:

   • Some recent movements focus on the problems caused by gentrification. Community groups are pushing for policies that keep affordable housing and prevent people from being forced out of their homes. For example, in San Francisco, housing costs went up by more than 50% from 2010 to 2020. Movements here led to new laws like rent control.

In conclusion, social movements significantly affect how cities develop. They advocate for fairness, sustainability, and strong communities, changing city planning ideas and making spaces more inclusive and just for everyone. Their influence shapes cities for future generations.
