Percent of Persons over Age 64
- The proportion of the population that is 65 years and older.
The percent of persons over age 64 is equal to the total number of aged persons 65 years and
older divided by the total population for each NSA.
Areas with higher percentages of persons over the age of 64 are given a high priority status
because these NSAs may require more services targeted to an aging population.

Percent of Persons Ages 5-19
– The proportion of the population that is between the ages of 5
and 19.
The percent of persons between ages 5 and 19 is equal to the total number of juveniles between
the ages of 5 and 19 divided by the total population for each NSA.
Areas with higher percentages of youth are given a high priority status because these NSAs may
require more services targeted to children and families.

Infant Wellness
– Score based on births to adolescents, low birth weight and no prenatal care in
the first trimester of pregnancy.
All 2011 birth records for the City of Chesapeake were address-matched and assigned to an NSA
using GIS. The point data was then analyzed in Excel to find the total number of births, the
number of children born to women under the age of 18, the number of babies that weighed 2,500
grams or less (approximately 5 ½ pounds), and the number of mothers who received no prenatal
care in the first trimester.
Each NSA is indexed based on the following criteria:
•
Age of Birth Mother
– If the age of the birth mother is less than 18 years, the birth is
given a score of 0. For births by mother 18 or older, the birth is given a score of 1.
•
Birth Weight
– If the birth weight equals or is less than 2,500 grams, the birth is given a
score of 0. If the birth weight exceeds 2,500 grams, the birth is given a score of 1.
•
Prenatal Visits
– If the mother had not prenatal visits in the first trimester, the birth is
given a score of 0. If the mother had at least one prenatal visit in the first trimester, the
birth is given a score of 1.
The maximum score for each birth is 3. The actual birth scores were averaged for each NSA. The
resulting number is the Infant Wellness score for the NSA.
