The passage of time brings new challenges for societies that, if not drawn, lead to a series of negative consequences, affecting their economic and social development. The laws appear throughout history as a regulator of human behavior, which must adapt to these challenges for society to prosper. this research seeks to analyze a fact constantly undervalued by the legal system despite its multiple negative consequences for the country: The over-population, understood as a demographic growth that is not supported economically and thanks to that, generales an imbalance already known since !he time of Thomas Malthus where poverty is deepened by the loss of purchasing power with inflation and economic development is slowed down. Despite the efforts made in the country wilh a view to reproductive sexual education, (currently insufficient) irs a fact that the most vulnerable sectors reproduce themselves in irresponsible numbers, affecting not only their own development and economy, but that of society in general. the present work, in need of an interdisciplinary perspective, seeks to show the causes and effects of reproduction that, being unable to be supported by the parents, becomes a problem of the State, studied from a constitutional perspective.
