4. Administrative birth records are compiled by the newest National Statistical Institute (INEGI) when you look at the Mexico and Ministry from Fitness. The information and knowledge include all births registered to help you get a good beginning certification. This type of management details become chronilogical age of mother within delivery, studies, relationship condition and you will venue regarding beginning (state and you can state). We use these ideas to render a standard photo of your own advancement of teenage pregnancies.

11. Some women have not dropped out-of-school, plus men and women instances we replace the destroyed worthy of to have dropout many years on the chronilogical age of anyone. Just like the the audience is together with dealing with getting years, it’s zero affect the fresh new rates.
