Overview of East Kalimantan’s Population in 2010 by Examining the Population Pyramid

To gain an understanding of East Kalimantan’s population in 2010, we use a population pyramid. A population pyramid typically illustrates the distribution of the population based on age and gender, age histograms for each gender grouped by age brackets, and the length of the histogram, which represents the number of people in an age group or the percentage of people in the total population.

Below is the population data table for the East Kalimantan Province in 2010, obtained from the BPS website.

Using Microsoft Excel software, we obtained the following pyramid shape.

From the population pyramid, it is evident that the pyramid has a wide base and a triangular shape with the pre-productive age group (0–14 years) consisting of 1,086,866 individuals, the productive age group (15–64 years) comprising 2,382,644 individuals, and the post-productive age group (65+) consisting of 83,633 individuals.

With a total population of 3,553,143 in East Kalimantan in 2010, the population is composed of 52.7% males and 47.3% females, with a sex ratio of 111, indicating that for every 100 female residents, there are 111 male residents.

Based on the dependency ratio, it is 0.5, which means that for every 1 non-productive age individual, there are 2 productive age individuals. This dependency ratio is relatively low due to not very high life expectancy and a consistently high population growth rate. Therefore, this pyramid represents a young population. In demographic transition like this, there is high fertility and mortality.
