For the first time in Brazil, more than 55% of the population is over 30 years old -IBGE
The data come from the Continuous National Household Sample Survey (PNAD Contínua), released this morning (22nd) by the Brazilian Institute of Geography and Statistics (IBGE).
In 2012, almost half of the population (49.9%) was under 30 years of age, a rate that decreased last year to 43.9%, representing about 92.7 million people.
“It is estimated that between 2012 and 2021, the population under 30 will not only show a decrease in its share of the total population, but also a negative change in absolute terms, with a decrease of 5.4% in the total number of people in this age group,” highlights an excerpt from the IBGE survey.

The survey found that the representativeness of all age groups under 30 has declined over the past decade.
IBGE highlighted the decline in participation in the 10- to 13-year-old group – from 6.7% to 5.5% between 2012 and 2021 – and also in the 14- to 17-year-old group, which saw a drop from 7.1% to 5.8% during that period.
On the other hand, the population aged 30 or more grew during the decade, reaching 119 million Brazilians. Particularly noteworthy is the percentage of people who are 60 years or older.
In 2021, this group will represent about 14.7% of the national population. Ten years ago, the figure was 11.3%. According to the IBGE, the number of people in this age group increased by 39.8% during this period.
“The analysis of the age structure of the resident population and the percentage participation of each age group by gender in 2012 and 2021 confirms the increase of the top and the decrease of the base of this structure, which shows the trend of population aging,” IBGE said.
Due to aging, the survey also shows news in the group that is economically dependent on a working family member.
Among children and adolescents, the rate decreased from 34.4 to 29.9 out of 100 between 2012 and 2021. Among the elderly, this rate increased from 11.2 per 100 to 14.7 per 100.
GROWING POPULATION
According to the IBGE survey, the country’s population increased by 7.6% during the decade, from 197.7 million in 2012 to 212.7 million in 2021.
The Midwest (13.0%) and the North (12.9%) experienced the largest increases, but they still account for the smallest shares of the total (7.8% and 8.7%, respectively).
The Southeast continues to be the most populous region at 42.1%, a 7.3% increase in the contingent over 2012.
IBGE notes that the estimates do not yet include the impact of the Covid 19 pandemic, which has led to an increase in deaths and a decrease in births. Therefore, the agency is counting on the next census, which begins in August, to update the projections.
BLACK AND MIXED-RACE PEOPLE
The PNAD also shows that the percentage of people who self-identify as black or mixed-race is increasing. For the former group, the index rose from 7.4% to 9.1% over a decade, and for the latter, from 45.6% to 47%. The proportion of white people in IBGE fell from 46.3% to 43% during this period.
According to IBGE data, the percentage of the population declaring themselves white has declined in all regions. The largest increase in self-identified blacks occurred in the Northeast (2.7 percentage points). The South saw the largest increase in people self-identifying as brown (3.2 percentage points).
“In absolute terms, the country’s resident population is estimated to increase by 7.6% between 2012 and 2021, while the population declaring itself black will increase by 32.4% and the brown population by 10.8% over the same period, while the population declaring itself white will not show significant changes,” the study states.
