World Population today is 7.12 billion, and by 2050 it will be 8.92 billion-plus. Almost half of the world lives on less than $ 2.50 a day, and four out of five are under $ 10 a day. Worldwide, some 830 million people live in urban slums, and by 2020, it is estimated that the world’s slum population will cross 1 billion. Every second person (50%) on the globe lives in urban areas. This is expected to reach 75% (which is 3 out of 4 persons) by 2050. Slum dwellers grew from 777 million to 830 million during 2000-2010. By 2030, around 40% of the world population, i.e., 3 billion-plus, will require basic urban infrastructure and housing. (In 2014, China had 758 million urban dwellers, India 410 million, USA 263 million.) The world needs 4,000 houses an hour to keep up with the demand (UN-Habitat). In view of this population and urbanization explosion.The percentage of people without access to decent, stable housing is rising. Adequate housing is vital to the health of the world’s economies, communities, and populations. If we are to succeed in the fight against poverty, we must support the expansion of housing both as policy as well as practice.
