Which of the following research methods would be most appropriate for studying the impact of housing vouchers on long-term health outcomes in a community?

To study the impact of housing vouchers on long-term health outcomes in a community, a longitudinal study would be the most appropriate research method. This type of study follows the same group of people over a period of time, allowing researchers to see how their health changes as they receive housing vouchers. For example, if researchers track a group of families who receive housing vouchers for several years, they can compare their health outcomes before and after they move into better housing. This method helps to establish a clear cause-and-effect relationship between housing conditions and health, providing valuable insights into how improving housing can lead to better health for community members. Overall, a longitudinal study offers the best chance to understand the long-term effects of housing vouchers on health.
