Life Expectancy at Birth (Years)
Life expectancy at birth indicates the number of years a newborn infant would live if prevailing patterns of mortality at the time of its birth were to stay the same throughout its life.

  World development Indicators: Technical Documentation -> Variable Descriptions -> Crude Birth (Rate per 1,000 People)
Crude Birth (Rate per 1,000 People)
Crude birth rate indicates the number of live births occurring during the year, per 1,000 population estimated at midyear. Subtracting the crude death rate from the crude birth rate provides the rate of natural increase, which is equal to the rate of population change in the absence of migration.
