- 1. The natural changes in a population www.indexmundi.com/map www.indexmundi.com/map www.indexmundi.com/map
- 2. The birth rate www.indexmundi.com/map www.indexmundi.com/map www.indexmundi.com/map <ul><li>The birth rate can be represented by number of childbirths in that year. This figure is combined with the death rate to produce the rate of natural population growth. </li></ul><ul><li>The formula for calculating the birth rate is: The number of births in a year x1000 The total population </li></ul><ul><li>Calculate the birth rate of Angola: - The number of births in 2007 was, 552772 - The total population of Angola is 12,531,357 </li></ul><ul><li>The answer: 44,09 per 1000 births </li></ul>
- 3. The fertility rate www.indexmundi.com/map www.indexmundi.com/map www.indexmundi.com/map <ul><li>The total fertility rate of a population is the average number of children that would be born to a woman over her lifetime if she were to experience the exact current age-specific fertility rates through her lifetime, and she were to survive from birth through the end of her reproductive life (15 to 49 years) . </li></ul><ul><li>The formula for calculating the birthrate is: </li></ul><ul><li>The number of births in a year x 1000 The total population </li></ul><ul><li>Calculate the birth rate of Spain: - In the year 2007, 554740 children were born in Spain - The population of Spain is 40,4920,051 </li></ul><ul><li>Answer: 1.37 children per women </li></ul>
- 4. The mortality rate www.indexmundi.com/map www.indexmundi.com/map www.indexmundi.com/map <ul><li>Mortality rate is a measure of the number of deaths (in general, or due to a specific cause) in some population, scaled to the size of that population, per unit time. Mortality rate is typically expressed in units of deaths per 1000 individuals per year; thus, a mortality rate of 9.5 in a population of 100,000 would mean 950 deaths per year in that entire population. </li></ul><ul><li>The formula for calculating mortality rate is the same as for the birth rate. </li></ul><ul><li>Calculate the mortality rate of The Netherlands - The amounts of deaths is a year is 134,827 - The Netherlands has 16,645,313 inhabitants </li></ul><ul><li>Answer: 8.1 </li></ul>
- 5. Infant mortality rate www.indexmundi.com/map www.indexmundi.com/map www.indexmundi.com/map <ul><li>Infant mortality is defined as the number of deaths of infants (one year of age or younger) per 1000 live births. The most common cause of infant mortality worldwide has traditionally been dehydration from diarhea . </li></ul><ul><li>The formula for the infant mortality rate is: The number of deaths of children less than a year old x1000 The total amount of births </li></ul><ul><li>Calculate the infant mortality rate of Sierra Leone: - The number of deaths among infants was in 2007, 45038 - The number of births in 2007 was, 283,264 </li></ul><ul><li>The answer: 156 deaths for every 1000 births </li></ul>
- 6. Exercises www.indexmundi.com/map www.indexmundi.com/map www.indexmundi.com/map <ul><li>Calculate the birth rate and the fertility rate of Europe if the population is 729,341,014, the number of births is 7,294,734, and the number of fertile women is 182,859,871. </li></ul><ul><li>Calculate the mortality rate of Africa if the population is 891,437,541, the number of deaths in a year is 12,402,815. </li></ul>
