Population Growth

It is also important in that it helps determine the dependency ratio. High population growth rate is usually a problem especially with limited resources in a society whereas low population growth rate is a problem in the society given that the society may face workforce shortages in the future. The paper discusses the population size of all US citizens as depicted by data from 1900 to 2000 census.
Data used in this paper was retrieved from the US census database. The reason for selecting this data was because of availability of data online, the convenience of the data source and to show how a developed country manages its population size through its policies and also to determine the expected population size in the next census. US Census data was retrieved for the year 1900 to 2000 from the US census website. The following is an analysis of the data.
From the year 1900 to 2000 the population increased by 205,628 thousand, the mean increase in population is for the ten year period from 1900 to 2000 is 20,563 thousand, the standard deviation of this increase in population 7064.3. We, therefore, expect that the population size will increase by 20563 thousand in 2010.
The composition of the population is an important measure in a society given that it helps determine the dependency ratio. The following chart shows the composition of the population as at the 1990 census
From the above chart, it is evident that the majority of individuals during the 1990 census were aged 15 to 34 years while only 21.06% were aged 55 years and above. Total workforce, therefore, was 57.4% and this means that approximately 42.6% of the population was dependent on the workforce.
From the above chart, it is evident that the majority of the individuals in this year were aged between 35 and 54 years and only 21.06% were aged above 55 years.
