Little-Known IBGE Ranking Reveals Economic Disparities Between Brazilian Municipalities, Highlights Maranhão City with Average Production Far Below National Average and Helps to Understand Limits of Per Capita GDP as Isolated Indicator of Local Reality.
In a country with over five thousand municipalities, not all rankings produced by official bodies reach the general public.
Some of them, however, help to understand how economic activity is distributed across Brazilian territory, especially when they reveal little-known realities outside their regional contexts.
This is the case of the segment that gathers municipalities with the lowest per capita GDP values.

New fuel prices were announced following government intervention, and the price of gasoline surprised those who expected a significant drop in the amount charged at Brazilian gas stations.
In the most recent edition available of the study GDP of Municipalities, prepared by the Brazilian Institute of Geography and Statistics (IBGE), Santana do Maranhão, in the interior of Maranhão, ranks first among the municipalities with the lowest Per Capita Gross Domestic Product in the country.
According to the institute’s official data, the indicator was calculated at R$ 5,407.66 per inhabitant for the base year considered by the survey.
The result stands out because it contrasts with the municipalities that usually make the economic news, generally associated with the presence of large industries, exploitation of natural resources, or high value-added activities.
In this case, the ranking highlights a set of cities with more limited productive structure, reflected in average economic production values.
What Per Capita GDP Measures — and What It Doesn’t Measure
Although presented as a “per inhabitant” value, per capita GDP does not correspond to individual income, average salary, or money available for consumption by the population.
It is a statistical indicator of average economic production, obtained by dividing the total GDP of the municipality by its resident population.
According to the methodology adopted by IBGE, GDP encompasses the value added by local economic activities, considering the production of goods and services and subtracting intermediate consumption.
The calculation allows comparisons between municipalities of very different sizes, but does not describe, in isolation, how this production is distributed among residents, businesses, or sectors.
For this reason, public statistics experts often emphasize that per capita GDP should be interpreted with caution.
Two cities with the same value may present very different social realities, depending on the composition of the local economy and how the generated wealth circulates internally.
Why the Ranking of Lowest Values Draws Attention
When IBGE releases the GDP of Municipalities, the extremes of the ranking tend to attract more interest.
On one side, there are cities with high values, often driven by specific activities and small populations.
On the other, municipalities with lower average economic production appear, as is the case with Santana do Maranhão.
This type of segment helps to highlight regional inequalities and differences in productive bases existing in the country.
By placing thousands of municipalities side by side, the survey provides a comparative view that would hardly be obtained through isolated analyses or data aggregated at the state or national level.
Maranhão Municipalities Have the Lowest Per Capita GDPs
In addition to Santana do Maranhão, the ranking of the lowest per capita GDPs released by IBGE includes two other municipalities from Maranhão in the following positions.
Primeira Cruz appears next, with a per capita GDP of R$ 6,394.30.
Matões do Norte registers R$ 6,694.14, considering the same base year of the study.
The concentration of municipalities from the same state in this segment does not, by itself, allow for conclusive explanations about local causes or dynamics.
IBGE itself emphasizes that the data indicates only the average level of economic production and does not replace more detailed analyses on employment, income, or living conditions.
Weight of Public Administration in the Local Economy
In the breakdown by major activity groups, IBGE points out that in the municipalities with the lowest per capita GDP values in that segment, Public Administration played a significant role in the composition of the added value.
This means that activities related to education, health, defense, and social security had a relevant participation in the final result.
According to institute technicians, this profile is common in municipalities where there is less presence of higher value-added private activities.
Nevertheless, the data does not allow one to infer, in isolation, how the local labor market or family income sources are organized.
Limits of Per Capita GDP for Assessing Quality of Life
Per capita GDP is widely used by public managers, researchers, and journalists due to its standardization and comparability.
However, it was not designed to measure well-being, quality of public services, or social inequality.
Indicators such as household income, education level, access to basic services, and informality in the labor market rely on other data sources and specific methodologies.
Therefore, analyses that seek to portray the social reality of a municipality often combine GDP with demographic and social information produced by IBGE itself and other public institutions.
Ranking Changes with New Editions from IBGE
Another relevant point is that the GDP of Municipalities is released by base year, following the institute’s official calendar.
This means that the position of each city in the ranking may change with each new edition as new data is incorporated.
For this reason, IBGE recommends that rankings always be contextualized to the period they refer to, avoiding treating the result as a permanent characteristic of the municipality.
Changes in the economic structure, population size, or methodology may influence values over time.
Statistical Curiosity and Public Interest
Rankings such as the lowest per capita GDPs tend to circulate more intensely when rediscovered outside the official release period.
Interest usually arises precisely from the combination of little-known numbers and the geographical diversity of the country.
Beyond the initial curiosity, the data can serve as a starting point for broader analyses, provided it is accompanied by explanations of its limits and meanings.
Without this care, there is a risk of simplified interpretations of an indicator that was created for economic comparisons, not to summarize the reality of a city.
Given this scenario, how do you evaluate the use of economic rankings in public debate: do they help to understand the inequalities in the country, or are they still interpreted too literally?
