Income Distribution in Malaysia

I always wonder what is the income distribution in Malaysia.
We always heard from the news that many EPF account holder do not earn enough to retire comfortably.

Malaysia has about 31.4 million people in 2017.
There are 30.7 million people in 2014.

According to the Economic Planningg Unit (EPU), about 45% of the population is earning at least RM5000 household income in 2014. That is not a very bad income. In 2004, there was only 16.8% of the population earning at least RM5000. Quite a huge improvement in 10 years.
