1B. NATALITY: MATERNAL CHARACTERISTICS ANDNEWBORN?SHEALTH
The
total fertility rate
(TFR) indicates
the average number of births to a
hypothetical cohort of 1,000 women,
if they experienced the age-specific
birth rates observed in a given year
throughout their childbearing years.
From 2000 to 2008, Arizona?s TFRs
always exceeded the rate of
?replacement? (2,110 births per
1,000 women,
Table 1B-1
). The
?replacement? rate is considered the
value at which a given generation
can exactly replace itself. The TFR
was 2,058 births per 1,000 women
of childbearing age in 2009 and
2010, decreasing to 1,981 in 2013.
The 2013 TFR of 2,386 for Black or
African American women exceeded
the generation replacement rate by
13.1 percent. The rate for White
non-Hispanic women (1,755) was
16.8 percent lower than the
replacement rate.

Note:

The sum of age group-specific birth ratesmultiplied by five (the number of years in the age group). The rate of 1,981
above for example, means that if a hypothetical group of 1,000women were to have the same birth rates in each age group
that were observed in the actual childbearing population in 2013, they would have a total of 1,981 children (or 2.0 children
each) by the time they reached the end of the reproductive period (taken here as age 50), assuming that all of thewomen
survived to that age.
Another measure used to summarize
reproduction patterns is the
gross
reproduction rate
(GRR). It
represents the average number of
daughters born to a hypothetical
cohort of 1,000 women if they
experienced the age-specific birth
rates observed in a given year
throughout their childbearing years.
This measure is similar to the total
fertility rate except that it measures
only
female
births,
since
reproduction is largely dependent on
the number of females in a given
population. In 2013, the gross
reproduction rates in Arizona ranged
from 853 for White non-Hispanic
women to 1,149 for Black women
(

Table1B-1
).

Notes:

The sum of birth rates by 5-year age groupsmultiplied by the proportion of births whichwere female. The gross
reproduction rate represents the average number of daughters born to a hypothetical cohort of 1,000women if they
experienced the age-specific birth rates observed in a given year throughout their childbearing years, and if none of the
cohort was to die during their childbearing years.
