3.1 AREA OF STUDY

The study area of the present work corresponds to the municipality of Rio de Janeiro in Brazil. The city is located in the southeast region of the country and is bathed by the Atlantic Ocean. Rio de Janeiro is the second-largest city in the country in terms of population, with about 6.7 million people (IBGE, 2020), distributed over an area of 1,200.33 km2, which results in a population density of 5,597.55 inh./km². The municipality area is administratively divided into five planning areas, subdivided into 16 planning regions, 33 administrative regions, and 163 neighborhoods (IPP, 2019). To evaluate the online survey results, the planning regions’ geographic division will be used, as they have a certain parity with the population’s socioeconomic conditions. In Figure 10 below, it is possible to see the city’s location in Brazil and the 16 planning regions used in the study.
