The city, in combination with localities forming the wider metropolitan area, is home to over 15 million . The population is growing by an estimated 4.2% per year, one of the highest rates among Asian cities. The continuing growth reflects ongoing migration from rural areas to the Dhaka urban region, which accounted for 60% of the city's growth in the 1960s and 1970s. More recently, the city's population has also grown with the expansion of city boundaries, a process that added more than a million people to the city in the 1980s. According to the ''Far Eastern Economic Review'', Dhaka will be home to 25 million people by the end of 2025.
