1. Why is it called a crude rate?

The crude birth rate (often referred to simply as the birth rate) is the most commonly used index of fertility. This is the ratio of the number of live births each year to the total population (usually measured at the mid-point of the year). It is expressed as the number of births per 1,000 population. e.g. if 3,000 babies were born in a population of 150,000, then the crude birth rate would be 20 per 1,000.

2. What aspect of population growth or decline is not measured by the natural increase calculation?

female fertility and infant mortality

3. Calculate the Birth and Death Rates for Ireland in each of the four years

1995: 13,54- 8,95

1998: 14,46- 8,47

2000: 14,32- 8,21

2002: 15,45- 7,49

4. Calculate the Natural Increase for Ireland in each of the four years.
1995-13,44
1998-14,46
2002-15,45

5. Write a short paragraph outlining the population changes experienced over the period from 1995 to 2002, based on this data.

la poblacion a incrementado devido a que la cantidad de personas nacidas por año a aumentado i la cantidad de muertes por año a disminuido, por esto la poblacion aunmenta.
