general population
There are currently 10.2 million people living in
Jakarta and that is why it is classified as a megacity. Jakarta's population has constantly and consistently grown over the past 100 years.
From this table we can see how rapidly the population of Jakarta has grown over the years. Source - http://www.worldpopulationstatistics.com/jakarta-population-2013/
Age and Sex of Jakarta's population
52.9% of the population are female and 47.1% are male.
39% are under 20 years of age, 42% are between 20 and 35 years old, 15% are
between 35 and 50, and only 4% are over 50. The reason that nearly half of Jakarta's population is between 20 and 35 is probably because the city offers many job opportunities and the people in that 20-35 age bracket are usually the most likely to be looking for work.

Housing in Jakarta
Jakarta is a massive city with a huge population, but where
do they all live? Many people in Jakarta live in apartments in the city. Many people
live in apartments because Jakarta has a big population, and the only way they
can fit everyone in is if they build up because they can’t build across.
Another form of housing in Jakarta are homes in villages called ‘kampungs’. These
houses in kampungs are detached homes that are usually just minutes away from
the city CBD. Finally, over half of Jakarta’s population lives in slums. In the
slums, sanitation and quality of life isn’t good, and space per person is at a
minimum.
This is an example of an apartment that many people with steady wages would live in. This apartment would probably be located near the city CBD. Source - http://www.homedesignfind.com/architecture/sneak-peek-at-the-nirvana-apartments-kemang-jakarta/
Here is a picture of a kampung. You can see how close the houses are together and how close the kampung is to the city. Source - https://geolocation.ws/v/P/17926146/kampung-bali-jakarta/en
Over half of the population of Jakarta live in slums and you can see the shocking conditions through this picture. Source - http://www.spraguephoto.com/stock-photography-image/6200/Garbage-clogged-canal,-Jakarta,-Indonesia.

Population Density
Jakarta's current population density is 14,464 people per square kilometre. This is a huge figure compare to Australia's 2.91 people per square kilometre. Jakarta is the 17th most densely populated city in the world which would mean that it would be an extremely busy city and at times could be very difficult to get around.
In this map we can see Jakarta inside the black circle. Its dark red colour suggests that the city is in the top bracket of population density in the whole of South-East Asia. Source - http://www.ncgia.ucsb.edu/pubs/gdp/pop.html
This map shows us the distribution of population density all over Jakarta. The darker the green colour, the more densely populated the area is. A lot of dark green patches are near Central Jakarta probably because that area is when the CBD is located, and that is where many people are attracted to.
