In 2022, there were 90.7 million housing units in the country, an increase of 34% agains the 2010 Census, when there were 67.5 million. Among the housing units enumerated in 2022, 90.5 million were permanent private ones and 72.4 million were occupied during the census operation, an increase of 26% in the same period. Improvised housing units amounted to 66 thousand and collective ones were 105 thousand. These are the first results of the 2022 Population Census, released today (28) by the IBGE.

This increase in the total number of housing units in the country is related to the significant increase in two categories: vacant housing units and those for occasional use. As for permanent private housing units, in which the two types are added up, the increase amounted to 80%, and reached 18 million in 2022. Vacant private housing units increased by 87%, and reached 11.4 million, whereas those for occasional use increased by 70% in 12 years, adding up to 6.7 million. The three municipalities with the highest percentage of vacant housing units are located in the Northeast São João do Jaguaribe, in Ceará (29.1%), Canavieira, in Piauí (28.1%) and Bom Sucesso, in Paraíba (27.2%).

“Vacant housing units are those that have no resident. Housing units for occasional use are those occupied part-time, such as summer houses. Since 2010, the increase of occupied housing units was bigger, in absolute figures; in terms of proportion, however, non-occupied housing units recorded a hgher increase in the period,” says the technical manager for the Census, Luciano Duarte.

According to the IBGE demographer Márcio Minamiguchi, besides the increase of vacant housing units and housing units for occasional use, what also accounts for the increase is the change in the structure of families in the country, who are present in a bigger amount of homes nowadays. “With the aging of the population, which is related to a lower fertility rate, it is natural to observe a decrease in the number of residents per housing unit. In the past there was a bigger number of families consisting of a couple with children and, usually, a lot of children. Nowadays there was a decrease in this type of arrangement, with an increase in participation of other arrangements, such as couples without children, single mothers and single-person families. As for couples with children, the number is smaller, usually one or two. That is, there was an increase in the number of arrangements with fewer people.”

As highlighted by the enumerator, the change also caused the decrease in the average number of residents per housing unit in the country, from 3.31 in 2010, to 2.79 in 2022. Although all the states had recorded a decrease in this average, those with a higher number of residents per housing unit are Amazonas (with a change from 4.36, in 2010, to 3.64, in 2022) and Amapá (from 4.26 to 3.63). The states with the lowest averages are Rio Grande do Sul (2.54), Rio de Janeiro (2.60) and Espírito Santo (2.67).

São Paulo concentrates most housing units

The number of housing units increased in all the states and in the Federal District. São Paulo, which concnetrated about one fifth of the Brazilian population (21.8%), had 19.6 million housing units in 2022, the biggest number among the states. Twelve years before, there were 14.9 million. The second most populous state is Minas Gerais, with 9.6 million housing units. Among the states with the smallest number of housing units are Roraima (211.9 thousand), Amapá (251.9 thousand) and Acre (319.3 thousand).

As it is the most populous city, the capital of São Paulo has the biggest number of housing units in the country, with 4.9 million. In comparison with data of 2010, when 3.9 million were enumerated, there was an increase of 27%. Of the 20 municipalities with the biggest number of enumerated housing units, the highlights were, besides São Paulo, Rio de Janeiro, Salvador, Brasília, Fortaleza and Belo Horizonte, all of them with increases above 20% against 2010. The five capitals had more than 1 million housing units on the reference date of the Census. Other municipalities recorded increases of more than 100% in this result, such as Abadia de Goiás, in Goiás, which went from 2,644, in 2010, to 7,866, in 2022 (197.5%).
