Parenthood decision-making: the Spanish case.

The birth rate cycle is changing in advanced societies as a result of the new ways of life. The decreasing trend in the number of new-borns can damage several social structures, such as the pension system. The aim of this project is to detect the variables that play a role when making the decision of having children as well as detecting those indicators that anticipates birth rates fluctuations. The effect of these indicators must be understood in order to implement efficient policies, as well as detecting as soon as possible the consequences that these approaches may lead into. Spanish data from google searches, macroeconomic indicators and answers from the CIS surveys are going to be analysed. The results are going be obtained using a number of ARIMA models.
