Question

This component of the population is the most fundamental and is often used by demographers in understanding the idea of fertility and mortality

Answer 1

Answer:

1 Sociologists measure fertility using the crude birthrate (the number of live births per 1,000 people per year). Just as fertility measures childbearing, the mortality rate is a measure of the number of people who die. The crude death rate is a number derived from the number of deaths per 1,000 people per year.

2 This entry focuses on the number of births per woman in a population. The most commonly used metric is the Total Fertility Rate (TFR) – or often simply 'fertility rate' – which measures the average number of children per woman. ... At that time the very high mortality at a young age kept population growth low
