# Population growth (annual %) - Asia

**Definition:** Annual population growth rate for year t is the exponential rate of growth of midyear population from year t-1 to t, expressed as a percentage . Population is based on the de facto definition of population, which counts all residents regardless of legal status or citizenship.

**Description:** The map below shows how Population growth (annual %) varies by country in Asia. The shade of the country corresponds to the magnitude of the indicator. The darker the shade, the higher the value. The country with the highest value in the region is Bahrain, with a value of 4.92. The country with the lowest value in the region is Syrian Arab Republic, with a value of -0.95.

**Statistical Concept and Methodology: **Total population growth rates are calculated on the assumption that rate of growth is constant between two points in time. The growth rate is computed using the exponential growth formula:
r = ln(pn/p0)/n,
where r is the exponential rate of growth, ln() is the natural logarithm, pn is the end period population, p0 is the beginning period population, and n is the number of years in between. Note that this is not the geometric growth rate used to compute compound growth over discrete periods.
For information on total population from which the growth rates are calculated, see total population (SP.POP.TOTL).

**Aggregation method: ** Weighted average

**Periodicity: ** Annual
