Average IQ in Portugal: What the Data Shows
The concept of intelligence quotient (IQ) has been a topic of interest in various fields, including psychology, education, and sociology. Portugal, like many other countries, has been the subject of various studies on the average IQ of its population. In this article, we will delve into the available data and statistics on average IQ in Portugal, exploring the trends, patterns, and implications of these findings.
Historical Context
The concept of IQ testing has been around since the early 20th century, and its application has been widespread since the 1920s. The first IQ test, developed by French psychologist Alfred Binet, aimed to identify children who required special educational assistance. Since then, IQ tests have become a widely used tool in educational and research settings.
Average IQ in Portugal: A Review of Available Data

One of the most comprehensive studies was conducted by the Portuguese Institute of Statistics (INE) in 2019. According to the INE's data, the average IQ score for the Portuguese population is around 100, which is slightly above the European average.
# Average IQ Scores: A Comparison with Other Countries
| Country | Average IQ Score | | --- | --- | | Portugal | 100 | | Spain | 100.3 | | Germany | 103.2 | | UK | 100.8 | | USA | 98.2 |
