1. Why is it called a crude rute.


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.
The crude death rate is the number of deaths per 1,000 members of a given population. It may be calculated for the population at the mid-point of the year or at the beginning of the year.


2.What aspect of population growth or decline is not measured by the natural increase calculation? The birth and the dead of the children

4. Calculate the Natural Increase for Ireland in each of the four years.

1995-48786,10424
1998-53599,15247
2000-54238,17835
2002-60520,25079

5. Write a short paragraph outlining the population changes experienced over the period from 1995 to 2002, based on this data. In 1995 the dead of the population was growth but in 2002 was very small that 1995. As the birth rate was very low in 1995 but has risen sharply until 2002, and the natural growth has been high in 2002.
