The term "tenement district" refers to a neighborhood that contains buildings that are often overcrowded and poorly maintained. Some synonyms for this term include "slum area," "ghetto," "shantytown," "low-income housing," "inner-city region," and "urban slum." These synonyms are often used interchangeably to describe areas with high poverty rates, inadequate housing conditions, and limited access to resources and services. As these neighborhoods often suffer from social and economic inequalities, it is crucial for policymakers to address their needs to improve the quality of life for residents.
