Index Mundi states that the last estimated birth rate in Brazil was 14.97 births per every 1,000 people in the Brazilian population as of 2013. The estimate, known as the crude birth rate, is taken at midyear.
Birth rates are generally a dominant factor when it comes to determining the rate at which a population is growing. These factors depend on the age structure and fertility of a population. According to NPR, Brazil has undergone a dramatic demographic shift. In the last 50 years, fertility rates have dropped from six children for each woman down to two or less on average.
