Since many years, urban planners and city makers are using average population growth and death for calculating the population increase for the next 20 years. This helps in preparing master plans and action plans to provide adequate amount of facilities and amenities for the residents. The graph illustrates the population trend in Scotland between the period of 1940 to 2020 using three indicators which are birth rate, population growth rate and death rate.
The comparison in the graph shows that the birth rate was the highest in 1940 whereas the death rate was also at it’s highest i.e. 1.5 percent. Since then, the trends in the population growth rate and birth rates is quite similar throughout the years. The rate of population increase dropped drastically in between 1940-1950 and then again in 1960s. A small rise can also be seen in the population increase during late 1970s, however, the reasons behind these ups and downs is yet unknown. Regarding the death rate, after it’s highest in 1940’s, the rate has consistently declined till late 1950’s. Subsequently, the death rate remain constant through late 20’s after which a rise can be seen again.
To sum it up, steady birth rates and population growth is an indication for higher education levels as well as family planning incentives. However, this could also indicate the lower statistics of marriage. The actual reasons behind these incline and decline is unknown through the graph, but through research one can find many factors for these statistics.
