In 1970 percent of total population living in Malaysia was 30% and reached about 40% in the year 1990. The proportion of residents increased significantly by 10% in each year reached 70% till the year 2010. In 2020 again percent of population grew in cities that was nearly 75%. The ration was gradually increased without decline. The projection of percentage of population will be increase about 85% in year 2040. Similarly, Indonesia saw remarkable increases in their urban population % raised from 15% to nearly 30% in year 2000. Again further growth reached about 50% In year 2020. The drastic rise in ratio of population will be faced to 60% in future in the year 2040.
Meanwhile in 1970, resident percent of Philippines and Thailand was about 30% and 20% respectively.In 1990 the Philippines raised to 45%. Then gradually decreased to 40% in year 2010 while the Thailand ration of population remained nearly constant till year 2020 about 30%. But in 2020 Philippines citizen ratio was increased about 42% and predict it will grow to 30% till year 2040. On the other hand it will also regain the percent 40 in year 2040.
