Notes:

* "Life Expectancy at age 75" and the "Probability of Surviving between Age 15 and Age 60" refer to the period 2005-2010. All other indicators are for 2010.

(1) This table includes 196 countries with a population of 100,000 or more in 2010.

(2) Age that divides the population in two parts of equal size, that is, there are as many persons with ages above the median as there are with ages below the median.

(3) The child dependency ratio is the ratio of the population aged 0-19 to the population aged 20-64.The ratio is presented as number of dependants per 100 persons of working age (20-64).

(4) The old-age dependency ratio is the ratio of the population aged 65 years or over to the population aged 20-64. The ratio is presented as number of dependants per 100 persons of working age (20-64).

(5) The total dependency ratio is the ratio of the sum of the population aged 0-19 and that aged 65+ to the population aged 20-64. The ratio is presented as number of dependants per 100 persons of working age (20-64).

(6) The average number of years of life expected by a hypothetical cohort of individuals age 75 who would be subject during all their lives to the mortality rates age 75 and above of a given period. It is expressed as years.

(7) Adult mortality, represented as the probability of surviving between age 15 and age 60 (45p15) per 1,000.
