The early prediction showed that the population will grow upto two-fifth percentage and around 45% for the year 2030 and 2040 respectively.
Secondly,the number of people of age 65 and over will have a minimal decrement at the end. However the percentage for the year 1960 was slightly more than one-half which has a small growth to three-fifth portion in the year 1970. Later,the data was stabilized at three-fifth percent for next decade which was fluctuating regularly at around 60% for the year 1980 to 2000. Furthermore, the data had declined with a certain quantity as if fell to 55% and one-half for the year 2010 and 2020 which was later predicted to be fallen to around two fifthportin for next two decade. Additionally, the population of age upto 14 years was initially one-third percent in the year1960 which was decreased to one-fourth percent in year 1970 and stable for a next decade. The number has been decreasing with a certain amount innper decade as it was one-fifth proportion,15%,13%,12% for year 1990,2000,2010 and 2920 respectively which had predicted to be stabilized at 10% for next two upcoming decade.
