Unless otherwise specified, all numbers and rates pertain to place of residence (not occurrence).

Early Neonatal Period
The period from birth to 6 days of age.
Hispanic or Latino includes persons of Mexican, Puerto Rican, Cuban, South or Central American, or other Spanish culture or origin, regardless of race. Non-Hispanic + Hispanic may not equal the total number of events due to persons of unknown ethnicity.
Infant Mortality Rate

International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM)
A statistical classification system, in use since 1979, that arranges diseases and injuries into groups according to established criteria. It is used to improve comparability of cause of death statistics reported by different governmental entities. Most ICD-9-CM codes are numeric and consist of three, four or five numbers and a description. The codes are revised approximately every 10 years by the World Health Organization and annual updates are published by the Health Care Financing Administration (HCFA), now the Center for Medicare, Medicaid Services.
International Classification of Diseases, 10th Revision, (ICD-10)
An alphanumeric coding scheme that replaces ICD-9, and used for mortality data since 1999. ICD-10 codes were developed by the World Health Organization Collaborating Centres for Classification of Diseases.
Late Neonatal Period
The period after birth 7 through 27 days of age.
Neonatal Period
The period from birth to 27 days of age.
Any county with 35,000 or more total population per year 2000 Census.
Percent by Cause
Formula = [The number of deaths from a selected cause / Total number of deaths] * 100.
Percent within State
Formula = [The number of deaths in a selected geography / Total number of deaths in the state] * 100.
Percent of Births within State
Formula = [The number of births in a selected geography / Total births in the state] *100.
Postneonatal Period
The period after birth 28 through 364 days of age.
Per the Federal Office of Management and Budget, Directive 15 (1997),
Both Numerator and Denominator can be Place, Race, Age, Time, Ethnicity, Sex-specific:
Rate = [ N PRATES-M / D PRATES ] * 1000
M - Measure(s)
N - Number of Infant Deaths
D - Number of Live Births
Rates that use Census Population Estimates in the denominator are unable to be calculated when the selected population is Unknown.
Any county with less than 35,000 total population per year 2000 Census.
