Opponents of abortion in Brazil break record and reach 61%


PoderData shows that percentages have fluctuated 3 percentage points upwards since January 2021; favorable are 24%

The number of people who say they are against allowing abortion in Brazil broke a numerical record in January: it is currently 61%. It has fluctuated 2 percentage points upwards since May 2022 and 3 percentage points upwards since the beginning of the historical series, in January 2021. The data are from research PowerDate held from January 27th to 29th, 2024.

Voters who say they are in favor of releasing the procedure total 24%. The percentages have remained unchanged for 2 years. In January 2021, the first time the question was asked to respondents, 31% supported allowing abortion in the country.

Brazilian legislation already allows the practice of abortion in 3 cases:

  • pregnancy resulting from rape;
  • risk to the woman’s life;
  • fetal anencephaly.

Despite the constant results of opinion polls indicating that the majority of Brazilians are against the liberalization of the practice, there is an action being processed in the STF (Supreme Federal Court) to discuss the decriminalization of abortion. The text was written by retired minister Rosa Weber, then rapporteur of the case, in September 2023. Before leaving the Supreme Court, she voted in favor of decriminalization.

However, the trial will not move forward anytime soon. This is because, unlike Weber, the issue is not a priority for the current president of the STF, Roberto Barroso, who has already declared that he is against abortion and said that there is no forecast for the issue to be discussed again by the Court.

The research was carried out by PowerDategroup company Poder360 Journalism, with its own resources. Data was collected from January 27th to 29th, 2024, through calls to cell phones and landlines. There were 2,500 interviews in 229 municipalities in the 27 units of the Federation. The margin of error is 2 percentage points. The confidence interval is 95%.

To reach 2,500 interviews that proportionally fill (as they appear in society) the groups by sex, age, income, education and geographic location, the PowerDate makes tens of thousands of phone calls. Often, there are more than 100 thousand calls until interviewees are found that faithfully represent the population as a whole. Find out more about the methodology by reading this text.


By stratifying the data by demographic groups, the PowerDate shows that the rate of people who are against allowing abortion increases among men (64%) and among elderly people aged 60 and over (66%).

Residents from all regions form a majority against the termination of pregnancy. The highest rates are in the South and Northeast, both at 64%. The regions with the lowest rates are the North and Central-West: 55%.

Those who say they are in favor fluctuate little, considering the specific margin of error of each stratum – greater than in the general stratum of the research as it considers a smaller group of interviewees. The percentages in all stratifications range from 22 to 31 points.


Among those who approve of the Lula government, 55% are against allowing abortion and 33% support it. Among those who disapprove, 16% are in favor and 68% are not.

The search PowerDate was carried out from January 27th to 29th, 2024. 2,500 people aged 16 or over were interviewed in 229 municipalities in the 27 units of the Federation. Parametric weighting was applied to compensate for disproportionalities in the variables of sex, age, level of education, region and income. The margin of error is 2 percentage points, plus or minus.

The interviews were carried out by telephone (for landlines and cell phones), using the URA system (Audible Response Unit), in which the interviewee listens to recorded questions and responds using the device’s keyboard. The study’s confidence interval is 95%.

To make reading easier, the search results have been rounded. Because of this process, it is possible that the sum of some of the results is different from 100. Differences between the total frequencies and percentages in variable crossing tables may appear due to non-response occurrences. This study was carried out with the company’s own resources.
