see Appendix I, Population Census and Population
Estimates.)
Resident population includes persons whose usual place
of residence (i.e., the place where one usually lives and
sleeps) is in one of the 50 states or D.C. It includes
members of the Armed Forces stationed in the United
States and their families. It excludes members of the
Armed Forces stationed outside the United States and
civilian U.S. citizens whose usual place of residence is
outside the United States. The resident population is the
denominator used to calculate birth and death rates and
incidence of disease.
Civilian population is the resident population excluding
members of the Armed Forces, although families of
members of the Armed Forces are included. The civilian
population is the denominator for rates calculated for the
National Hospital Discharge Survey and for emergency
department visit rates using the National Hospital
Ambulatory Medical Care Survey—Emergency
Department Component.
Civilian noninstitutionalized population is the civilian
population excluding persons residing in institutions
(such as nursing homes, prisons, jails, mental hospitals,
and juvenile correctional facilities). U.S. Census Bureau
estimates of the civilian noninstitutionalized population
are used to calculate sample weights for the National
Health Interview Survey, the National Health and
Nutrition Examination Survey, and the National Survey of
Family Growth, and as denominators for rates calculated
for the National Ambulatory Medical Care Survey and the
National Hospital Ambulatory Medical Care
Survey—Outpatient Department Component.
Postneonatal mortality rate—See Appendix II, Rate: Death
and related rates.
Poverty—Two related versions of federal poverty measures
are shown in Health, United States. The first measure—a ratio
of family income to federal poverty threshold—is
constructed using poverty thresholds from the U.S. Census
Bureau. Poverty thresholds are updated annually for
inflation by the Census Bureau using the Consumer Price
Index for all urban consumers (CPI–U). Poverty thresholds
include a set of money income thresholds that vary by
family size and composition but do not vary geographically.
Families or individuals with income below the appropriate
threshold are classified as below poverty. For example, the
average poverty threshold for a family of four was $23,834 in
2013, $22,314 in 2010, $17,603 in 2000, and $13,359 in 1990.
For more information, see the U.S. Census Bureau's poverty
threshold website at: http://www.census.gov/hhes/www/
poverty/poverty.html.
The second poverty measure used in Health, United States is
a ratio of family income to the HHS poverty guidelines.
Poverty guidelines are derived from the U. S. Census
Bureau's poverty thresholds, are issued annually by HHS,
and are often used to determine eligibility in certain federal
programs. The HHS poverty guidelines take into account
family size and state (coterminous, Alaska, Hawaii), but not
family composition. For more information, see HHS. Office of
the Assistant Secretary for Planning and Evaluation. Poverty
Guidelines, Research, and Measurement website at:
http://aspe.hhs.gov/poverty/index.cfm.
National Health Interview Survey (NHIS)—For data years
prior to 1997, a ratio of family income to U.S. Census
Bureau poverty threshold is computed taking into
account family income and family size. Starting with
1997 data, the poverty ratio was based on family income,
family size, and family composition (number of children
in the family, and for families with two or fewer adults
the age of the adults in the family). (Also see Appendix II,
Consumer Price Index [CPI]; Family income; and
Appendix I, Current Population Survey [CPS]; National
Health Interview Survey [NHIS].)
National Health and Nutrition Examination Survey
(NHANES)—NHANES uses the U.S. Census Bureau's
Current Population Survey (CPS) definition of family to
group household members into a family unit. A poverty
ratio is computed by dividing family income by the HHS
poverty guidelines specific to family size, as well as the
appropriate guideline year, and state. See: Johnson CL,

Nutrition Examination Survey: Analytic guidelines,

Preferred provider organization (PPO)—A PPO is a type of
medical plan in which coverage is provided to participants
through a network of selected health care providers, such as
hospitals and physicians. Enrollees may seek care outside
the network but pay a greater percentage of the cost of
coverage than within the network. (Also see Appendix II,
Health maintenance organization [HMO]; Managed care.)
Prevalence—Prevalence is the number of cases of a disease,
number of infected persons, or number of persons with
some other attribute present during a particular interval of
time. It is often expressed as a rate (e.g., the prevalence of
diabetes per 1,000 persons during a year). (Also see
Appendix II, Incidence.)
Primary care specialty—See Appendix II, Physician
specialty.
Private expenditures—See Appendix II, Health
expenditures, national.
Procedure—Procedures can include surgical procedures
(such as appendectomies), diagnostic procedures (such as
spinal taps), and therapeutic treatments (such as infusion of
a cancer chemotherapeutic substance) reported on a
patient's medical record. In Health, United States, procedures
are currently coded according to the International
Health, United States, 2014 Appendix II. Definitions and Methods 435
