The growing trend in the southern hemisphere of incorporating workers with lower educational levels into the informal economy has raised concerns, especially in Colombia, where between 50% and 74% of workers lack adequate contractual conditions. There is a close relationship between informality and the educational level, with informal employment being the one that hosts the largest proportion of people with low levels of education, generating conditions of poverty or economic vulnerability, especially in Latin America.

The construction sector, vital for GDP and employment, attracts workers with little academic training, raising concerns about occupational health, occupational risks, and informality. The objective of this article is to present statistics of occupational accidents in the formal sector in various regions of the country, through a correlation between accidents in the formal and informal sector and to make a statistical inference where the accident rate in the informal sector is established, raising the urgency of specific strategies to improve the working conditions of workers in this sector.
