In 2010, the population of the city of Dhaka has been projected at 17.6 million people, with up to 60% in the slums. Every day we observe the influx of hundreds of new people to the city of Dhaka. But why do people come to Dhaka and other cities in Bangladesh? There are two factors behind it: a) pull factor and b) push factor. Bangladesh is urbanizing fast. People are moving to places where there are or are perceived to have jobs and opportunities. The cities are the new centers of jobs and opportunities. The bigger the center, the stronger the pool.
