==Definition==

The term '''adjusted total fertility rate''' or '''tempo-adjusted total fertility rate''' refers to a modified form of the [[total fertility rate]] that accounts for the [[tempo effect]] in a manner that provides (arguably) a better estimate of the [[completed fertility rate]] in the long term.

The standard definition of [[total fertility rate]] is that it is the sum of the [[age-specific fertility rate]]s for all ages. Alternatively, it is the number of live births a hypothetical woman would have if she passed through her [[childbearing years]] conforming to the age-specific fertility rate of this particular year. If age-specific fertility rates hold constant over time, i.e., in the absence of [[tempo effect]]s, the total fertility rate would equal the [[completed fertility rate]] for a [[birth cohort]] of females who have completed their childbearing years.

In the presence of tempo effects, we expect that age-specific fertility rates will change over time. The ''tempo-adjusted'' total fertility rate attempts to use data measuring the number, nature, and temporal distribution of live births ''in the current year only'' to estimate how these changes will unfold.
