Modelling (Spreadsheet Modelling for OR) - Essay Example

From the above chart it is clear that there has been an increase in population among the age 20 to 25 than any other age group, this is a positive indication of the population because this shows an increase in the regions workforce. The above chart shows that there has been a population increase among the young females, however there has been a decline in population among those aged above 40 years, this is evident from our above chart which shows higher death rates among the old yet a very low levels of population aged between 40 years and above.

The total rate from our data shows that the death rate total amounts to 1181.5 while that of the birth rate amounts to 871, when we proceed and find the mean rates then our mean death trate is equal to 69.5 while our birth rate mean is equal to 124.4286, this clearly shows that the population birth rate is higher than the population death rate, for this reason therefore it is evident that there is population growth in our region: From the above chart it is evident that there is positive and yet high population growth in the country, for this reason therefore as predicted.

The above chart shows that there has been a population increase among the young females, however there has been a decline in population among those aged above 40 years, this is evident from our above chart which shows higher death rates among the old yet a very low levels of population aged between 40 years and above. Total birth rate and death rate:The total rate from our data shows that the death rate total amounts to 1181.5 while that of the birth rate amounts to 871, when we proceed and find the mean rates then our mean death trate is equal to 69.

5 while our birth rate mean is equal to 124.4286, this clearly shows that the population birth rate is higher than the population death rate, for this reason therefore it is evident that there is population growth in our region:Death rateBirth ratetotal1181.5871mean69.5124.4286From the above chart it is evident that there is positive and yet high population growth in the country, for this reason therefore as predicted by Malthus the population in this region is growing at a Malthusian growth rate, for this reason therefore there is need to apply checks on the population, Malthus predicted that if the population was to grow at this rate then the result would be that there would occur natural ways to check population, positive check According to Malthus a country would grow in an arithmetic progression while the population will grow in geometric progression, for this reason the economy will not be in position to offer its citizens enough for survival and there will occur natural checks such as famine, malnutrition and other miseries.

For this reason therefore to avoid such disasters there is need to undertake such as family planning, late marriages and sex
