The World of Science is surrounded by correlations [ 1 ] between its variables. This is why the growing importance of Data Scientists, who devote much of their time in the analysis and development of new techniques that can find new relationships between variables. Under this precept, the article presents a correlation analysis for the period of time between life expectancy defined as the average number of years a person is expected to live in given a certain social context and fertility rate average number of children per womanthat is generally presented in the study by Cutler, Deaton and Muneywith the main objective of contributing in the analysis of these variables, through a more deeper review that shows if this correlation is maintained throughout of time, and if this relationship remains between the different countries of the world which have different economic and social characteristics.

The results of the article affirm that this relationship does indeed hold as much in time as between developed and developing countries, as is the case of Bolivia, which showed a notable advance in best vegan vegetarian restaurants nyc improvement of the variables of analysis.

The general idea of the analyzed correlation holds in general terms that a person with a high level of life expectancy is associated with a lower number of children compared to a person with a lower life expectancy, however this relationship does not imply that there is a causal relationship [ 2 ], since this relation can also be interpreted from the point of view that a what does base times height mean with a lower number of children, could be associated with a longer life expectancy.

Given this correlation, it is important to understand what are the possible channels or reasons for this particular phenomenon to occur [ 3 ]. Following the analysis, Figure 2 shows the evolution of the relationship between the selected variables over time, for all the countries from American during the period The fertility rate between the periodpresents a similar behavior that ranges from a value of 4 to 7 children on average.

Another issue to be highlighted is how the correlation between the analysis variables loses strength over time, this due to the reduced dispersion of data incompared to the widely dispersed data recorded in One of the main problems in a correlation analysis apart from the issue of causality already described above, is to demonstrate that the relationship is not spurious.
