They are presented as number of dependants per 100 persons of working age (25-64). c The child dependency ratio is the ratio of the population aged 0-24 to the population aged 25-64. They are presented as number of dependants per 100 persons of working age (25-64). d The potential support ratio is the ratio of the population aged 25-64 to the population aged 65 years or over. They are presented as number of dependants per 100 persons of age 65 years or over. e The population doubling time corresponds to the number of years required for the total population to double in size if the annual rate of population change would remain constant. Doubling time is computed only for fast growing populations with growth rates exceeding 0.5 per cent. Thailand Population: Total population and distribution by age and sex estimated to be consistent with the population by age and sex of the (a) 1960, 1970, 1980, 1990, 2000, 2010 censuses; (b) 1955-1956 DES and 1995-1996, 2005-2006, 2015-2016 SPC survey estimates; and with estimates of the subsequent trends in fertility, mortality and international migration. In addition, the only total population for 1947 Census have been considered. Fertility: Total fertility rate and age pattern of fertility based on: (a) official estimates of age-specific fertility rates through 2016; (b) registered births classified by age of mother and the underlying female population by age through 2016; (c) adjusted for underregistration; (d) birth-histories data from the 1974-1975, 1975-1976, 1985-1986, 1989, 1991, 1995-1996 SPC and 1975 WFS and 1987 DHS; (e) births in the household in the preceding 12 (or 24) months classified by age of mother from the 1960, 1970 censuses and 1964-1967, 2005-2006, 2015-2016 SPC and 1969-1970, 1972-1973 LSSEDCT and 1975 WFS and 1978, 1981, 1984, 1996-1997 CPS and 2005-2006, 2012, 2015-2016 MICS and 2006 RHS; (f) adjusted fertility using Brass P/F ratio method (or variants) with data on children ever born and births in the preceding 12 (or 24/36) months, both classified by age of mother, from the 1960 Census; (g) adjusted fertility using Arriaga modified P/F ratio method with data on children ever born and births in the preceding 12 (or 24/36) months, both classified by age of mother, from the 1960, 1970 censuses and 1972-1973 LSSEDCT and 1975 WFS; (h) indirect estimates obtained using Mortara's method with data on children ever born by age of mother from the 1960 Census; (i) indirect estimates based on the increment of cohort parities between successive censuses or surveys such as the 1970 Census and 1974-1975 SPC; (j) indirect estimates obtained from the application of the own-children method of fertility estimation to the 1970 Census; (k) International estimates considered up to 2017.
