The document describes polynomial fits and predictions made to population estimates from Cambodia between 1953-1988. Polynomial equations were used to generate low, mid, and high population estimates based on data from censuses and different historical periods of Cambodia. Predictions of future population from 1971-1988 were also made using polynomial fits to population projections found in other literature.

2. 1. Population estimates are given on lines 605 of table 4.1. See chapter text for an explanation of the calculations.
2. These are best fits to the population estimates calculated from polynomial equations. Their degree is given in the following footnotes.
3. Low from a 6th degree equation of rolling averages (period 3); mid-fit and high are from 4th degree equations of annual averages.
4. Low, mid, and high fits from a 4th degree equations of annual averages.
5. Low from a 3th degree equation of rolling averages (period 3); mid-fit and high are from 3th degree equations of annual averages.
6. Mid-value from a 4th degree equation of rolling averages (period 3); low and high are from 4th and 5th degree equations, respectively, of annual averages.
7. These are fits to population projections given in the literature – see table 4.1, lines 777-788. The fit is of a first degree linear equation.
8. Predictions are to 1971-1988 population. Low, mid, and high predictions are from 2th degree equations of annual averages.
