Demographics

In this this blog we will talk about the number of people living in Indonesia, where they are living (since Indonesia is kind of different geographically, compared to other countries) and the age structure. Getting curious already?

Let’s find out!

Map of Indonesia (very useful for a country like Indonesia!)

THE POPULATION

Population distribution
Indonesia is a country that consists of about 17,500 islands, many is it? However, “only” 6,000 of them that are inhabited. The five main islands are Sumatra, Java, Kalimantan (Borneo), Sulawesi, and New Guina, and two major archipelagos; Nusa Tenggara and the Maluku Islands. Indonesia is the world’s fourth most populated country, but there are very large differences between the population of the different islands. About 60% of the country’s population lives on Java and it is one of the most densely populated areas in the world. Let’s see how the population was distributed in 2013…

So what did you noticed? Did you compared the number of people living in certain areas/islands and looked at the map to have an idea of the sizes of these areas/islands? Many people live in areas which are actually far smaller than the areas where less people live is it?! For example, West Papua where the minority of Indonesian inhabitants live is much bigger than West Java where the majority of inhabitants live.

So let’s integrated this information into one map, to see the population density. The population density shows the average number of the population per 1 square kilometer.

Now we can see it even more clear: in the larger areas the population density is less than 35 per square kilometer. In the smaller areas the population density can be even more than 250 per square kilometer. We now know that this is not only due to the fact that these areas are smaller, but more due to the fact that many more people live in these areas.

Age structure
Wondering how old the 258,316,051 inhabitants are on average?
Well, the majority of the Indonesians (42,35%) are between 25 and 54 years old, about a quarter between 0 and 14 years and the minority of the population (6,79%) is 65 years and older, followed by the group Indonesians between 55-65 years old with 8.4% of the population. And last, but not least, we have the group between 15 to 24 years old, which is about 17,03% of the Indonesian population. So, now you can do the calculation of the average yourself ; )
But we can also visualize it, by making a population pyramid…

The pyramid and the percentages showed us that Indonesia has quite high number of young inhabitants. The body of the pyramid is wide, which reflects an increase of life expectancy and an increase of wealth and health condition.

  1. Hi Jessica, nice blog! But a question: is see that the oldest people (65 years and older people) are in the minority compared with the other ages. And that the pyramid reflects a increase in life expectancy. But what is the life expectancy of the Indonesian people now?
