This text is a fragment of the work "Education and labor income in Peru", carried out by the authors with financing from the IECOS 2007 Competitive Fund. This section explains the Human Capital Theory according to which education is an investment to increase productive capacity. This theory makes it possible to use accessible empirical sources and calculate the real impact of education on income. The econometric estimates are made for the country as a whole and for three segments: area, sex and type of work. In a second section, there is an account of the studies carried out in Peru on education and the labor market.

A complex sample design is developed to estimate the radio audience rating through a Panel Survey applied five times a year. The purpose of this design is the inclusion of segmentation variables such as sex, age, and family category, which gives rise to a two-stage cluster sampling and different stratification variables. In the first stage, clusters of equal size of 150 dwellings each will be selected via stratified sampling; in the second stage, two dwellings will be selected for each cluster through simple random sampling.

The objective was to relate eating habits with the body mass index and physical activity of university students. 237 students from the National University Federico Villarreal and 163 students from the National University of Engineering were surveyed in 2022, using an online form whose items were distributed in demographic data to characterize the students and their eating behavior (EB). Th e Likert scale was used. Th e data was analyzed with Microsoft Offi ce Excel updated to 2023. It was found that the average Body Mass Index (BMI) of the students is 24.5, falling within the normal classifi cation, they tend to eat more foods prepared at home, the Nutritional quality is subject to accessibility due to time and money; they usually consume lunch, omitting other meals. A low percentage considers they have Good eating habits. For the study group, physical activity was reduced during the dev...
