Methodology and Sources

Data and information used in the 1999 Oklahoma KIDS COUNT Factbook came from a wide variety of sources in Oklahoma and around the nation. This section identifies the sources for the information found in this document and the method used for computations where applicable. Each county benchmark and the rate of change calculated for each county benchmark is rounded for presentation on the county pages. The rounding may cause the results to vary from the rates which might be calculated from the numbers appearing on each county page.

There is no agreement about the specific terminology or the number of categories which should be used to classify race and ethnicity. The categories listed in this report are the categories in the sources relied upon for information. At times different sources will use different categories to report racial characteristics. Some indicators were not available by race at all. This makes it difficult to look across the indicators by race. Persons within each race or ethnic group are encouraged to re-title or refer to the data in a manner which reflects their preferences.

Extreme caution should be used when reviewing, using and comparing data related to Hispanic populations. Some agencies count Hispanic children as a race and others consider Hispanic to be a nationality whose children can be any race (White, African American, Native American, and so on). Of those counting Hispanic children as a nationality, only a few maintain statistics on the proportion of children who are Hispanic.

As a result, when Hispanic is considered to be a race, data may appear as follows:

  • White 70.0%
  • Native American 10.0%
  • American Indian 10.0%
  • Hispanic 5.0%
  • Asian 2.0%
  • Other 3.0%
    • TOTAL 100.0%


When Hispanic is considered to be a nationality, data may appear as follows:

  • White 72.0%
  • Native American 11.0%
  • American Indian 11.0%
  • Asian 2.0%
  • Other 4.0%
    • TOTAL 100.0%
  • Hispanic 5.0%
  • non-Hispanic 95.0%
    • TOTAL 100.0%

Economic Distress is a generalized term depicting a poor economic climate in a community. Deprivation Index is a measure developed by ranking Child Poverty Rates, Percent of Children receiving Aid to Families with Dependent Children (AFDC) and/or Temporary Assistance to Needy Families (TANF), level of Per Capita Personal Income and Unemployment Rates. Each county is ranked on each factor. The four individual county rankings are combined into a Deprivation Index in which the lower the number, the wealthier the county. Economic Clusters (more commonly referred to as Quintile Divisions) result from each county being ranked according to its Deprivation Index and grouped into one of five clusters composed of approximately twenty percent (20%) of the state’s population.

Cluster 1 (Wealthiest) includes 21 counties with a combined population of 733,823 (22.1% of the state’s population). “Wealthiest” counties each have a Deprivation Index between 23 and 91.

Cluster 2 (Wealthier) includes 8 counties with a combined population of 716,245 (21.6% of the state’s population). “Wealthier” counties each have a Deprivation Index between 95 and 119.

Cluster 3 (Middle) includes 2 counties with a combined population of 696,517 (21.0% of the state’s population). “Middle” counties each have a Deprivation Index between 130 and 140.

Cluster 4 (Poorer) includes 19 counties with a combined population of 583,134 (17.6% of the state’s population). “Poorer” counties each have a Deprivation Index between 141 and 181.

Cluster 5 (Poorest) includes 27 counties with a combined population of 587,372 (17.7% of the state’s population). “Poorest” counties each have a Deprivation Index between 183 and 297.

Children in Poverty counts the related children under age 18 who live in families with incomes below the U.S. poverty threshold (poverty income guidelines). Related children are the children related to the “family head” by birth, marriage or adoption and include relatives such as nieces and nephews. Children under age 18 who do not live in a household where they are related to the head of the household are not included in this analysis. The Poverty Income Guidelines, as defined by the U.S. Office of Management and Budget, are based upon the amount of money that is required to purchase a nutritionally adequate diet. A family is classified as poor if its income falls below this minimum standard. Data counts poor children calculated as a percent of all children. Trends compare percent of child poverty in 1980 to the percent of child poverty in 1993 as estimated by U.S. Bureau of the Census, Small Area Income and Poverty Estimates Program: State and County Income and Poverty Estimates - 1993.

Children Receiving AFDC and/or TANF counts the number of child recipients of AFDC during FY 1981 and the average monthly number of child recipients of TANF during FY 1997. Rates are displayed as the percent of the total child population. Base child population data for the state and counties is the 1980 Census population. Current child population data for the state and counties is estimated by the U.S. Bureau of the Census for 1997.

Per Capita Personal Income measures income available to each individual by dividing the total personal income in an area by the population of that area. Base data is for 1980; current for 1996.

Unemployment Rate measures the percent of the population searching for work. The rate is generated by dividing the total number of unemployed by the total number in the labor force. Because these official figures do not distinguish between part-time and full-time workers, do not count underpaid working poor and do not count workers who have given up looking for work, they are commonly understood to underestimate the true level of unemployment in a community. Base data is for 1980; current for 1997.

Child Population is the total resident population under age 18 including dependents of Armed Forces personnel stationed in the area. Child population data for 1980 and 1990 for the state and counties are counts from the 1980 and 1990 Census. Current child population data for the state and counties is estimated by the U.S. Bureau of the Census for 1997.

Low Birthweight Infants are live births weighing under 5.5 pounds (2,500 grams). Very Low Birthweight Infants are live births weighing under 3 pounds, five ounces (1,500 grams). The data is reported by place of mother’s residence, not place of birth. Births count both the total resident live births and the low-weight births and compare two five-year periods (1983 through 1987 and 1992 through 1996). Resulting rates create average annual percentages for each five-year period. Race is reported as White, Black and American Indian. Other races are included in numbers and calculations for White. Beginning in 1989, the “race of child” was redefined to reflect the mother’s race. State totals may vary from the total of all the counties since state totals may include births for which the county of residence was unknown.

Level of Prenatal Care addresses the timing and amount of medical care and monitoring an expectant mother receives. Levels of care include: adequate (the recommended level of care beginning in the first trimester with ten or more visits), intermediate (care beginning in the first trimester with four through nine visits OR care beginning in the second trimester with four or more visits), early (care beginning in the first trimester), late (care beginning in the third trimester with one or more visits), little (care beginning in the first or second trimester with one through three visits), and no care. Rates are calculated as percentages of all live births. Births count both the total resident live births and the level of care for the five-year period from 1992 through 1996. Resulting rates create an average annual percentage.

Infant Mortality is death occurring to an infant under 1 year of age. The data is reported by place of mother’s residence, not place of birth or death. Rates are calculated per 1,000 live births. The data counts the total resident live births and the deaths for two five-year periods (1983 through 1987 and 1992 through 1996). Resulting rates create average annual percentages for each five-year period. Race is reported as White, Black and American Indian. Other races are included in numbers and calculations for White. Beginning in 1989, the “race of child” was redefined to reflect the mother’s race. State totals may vary from the total of all the counties since state totals may include births for which the county of residence was unknown.

Births to Young Teens are live births which occur to mothers ages 15 through 17. The data is reported by place of mother’s residence, not place of birth. Births count the total resident live births to mothers in this age group for two three-year periods (1981 through 1983 and 1994 through 1996). Rates are displayed as births per 1,000 females between ages 15 through 17. Base female teen population data is from the 1980 Census. Current population for the state is estimated by the U.S. Bureau of the Census and adjusted by the Oklahoma State Department of Health to arrive at 1994 through 1996 estimates of females between the ages of 15 through 17 for the state and each county. Resulting rates create average annual rates for each three-year period. Race is reported as White, Black and American Indian. Other races are included in numbers and calculations for White. Beginning in 1989, the “race of child” was redefined to reflect the mother’s race. State totals may vary from the total of all the counties since state totals may include births for which the county of residence was unknown.

Child Abuse and Neglect means harm or threatened harm to a child’s health or welfare by a person responsible for the child’s health or welfare. Abuse includes sexual abuse, sexual exploitation or non-accidental physical or mental injury. Sexual Abuse includes rape, incest and lewd or indecent acts or proposals by a person responsible for the child’s welfare. Sexual Exploitation includes a person responsible for the child’s welfare allowing or encouraging a child to engage in prostitution or pornography or engaging in child pornography. Neglect means failing to provide adequate food, clothing, shelter or medical care. 10 O. Supp. 1996 section 7102. Data includes reports of suspected abuse or neglect for which there were formal investigations and, of those, the number for which abuse or neglect was confirmed. The data compares child abuse and neglect confirmations for two one-year periods (Fiscal Year 1985 and Fiscal Year 1997). Rates are displayed as confirmations per 1,000 children (under age 18). Base child population data for the state and counties is the midpoint between the 1980 and 1990 Census populations. Current child population data for the state and counties is estimated by the U.S. Bureau of the Census for 1997.

Child Deaths are the number of deaths of children from ages 1 through 14. Teen Deaths are the number of deaths of youth from ages 15 through 19. The data is reported by place of residence, not place of death. The data counts deaths from all causes. The data compares the death rates for two five-year periods (1978 through 1982 and 1992 through 1996). Resulting rates create average annual rates for each five-year period for each age group. Rates are displayed as deaths per 100,000 children from ages 1 through 14 and deaths per 100,000 teens from ages 15 through 19. Base child population data for the state and counties is the 1980 Census population. Current child population data for the state and counties is estimated by the U.S. Bureau of the Census for 1997 and adjusted by the State Data Center to arrive at a 1997 estimate of the number of children from the ages of 1 through 14. Current teen population data for the state is estimated by the U.S. Bureau of the Census for 1997 and adjusted by the State Data Center to arrive at a 1997 estimate of the number of teens from the ages of 15 through 19. State totals may vary from the total of all the counties since state totals may include deaths for which the county of residence was unknown.

Cause of Death measures the percent of deaths that are caused by diseases, accidents and violence. By definition, deaths by violence include murder, suicide and deaths that occur during legal interventions. Race is reported as White, Black and American Indian. Other races are included in numbers and calculations for White.

A family is classified as poor if its income falls below this minimum standard. Data counts poor children calculated as a percent of all children. Trends compare percent of child poverty in 1980 to the percent of child poverty estimated and revised by the U.S. Bureau of the Census for 1993. The data describes poor children calculated as a percent of the children in each race. For census purposes race is self-identified in one of four categories: White, Black, Indian (American Indian or Alaska Native), and Asian (or Pacific Islander). Hispanic Origin is counted separately and as an ethnicity, not as a race. Other includes races not selected and other races written in.

High School Dropouts count youths of any age who quit school without graduating. The data presents the number of high school dropouts for the 1996-97 school year. The data also presents the total number of high school dropouts who are under the age of 19.

High School Dropout Rates compare number of high school dropouts under age 19 to the enrollment in grades 9 through 12. School officials in Oklahoma are required to notify the State Department of Education of the name, address, race and age of any pupil dropping out of school. 70 O.Supp. 1996 section 35e(A). Race is reported as White, Black, Indian, Asian and Hispanic. There is no provision for reporting other races. Hispanic children, for the purposes of this data, are counted as a race, rather than an ethnic group preventing precise racial comparisons between this data and other data in the Oklahoma KIDS COUNT Factbook.

Juvenile Violent Crime counts arrests of youth from the ages of 10 through 17 for violent offenses (homicide, forcible rape, robbery, or aggravated assault). The annual arrest figures include all arrests for violent offenses during the year, including repeated arrests of the same individual for different offenses. Rates compare the number of arrests of youth ages 10 through 17 for violent offenses (homicide, forcible rape, robbery, or aggravated assault) to all children ages 10 through 17 and is reported as a rate per 100,000 youths. The data compares juvenile violent crime rates for two one-year periods (1980 and 1997). Base child population data for the state and counties is the 1980 Census population. Current child population data for the state and counties is estimated by the U.S. Bureau of the Census for 1997 and adjusted by the State Data Center to arrive at a 1997 estimate of the number of children from the ages of 10 through 17. Increases in the number of arrests may reflect increases in juvenile crime, changes in police activity and changes in public policy. While policies and practices regarding juvenile arrests may vary from county to county and city to city, it is widely believed that the policies are more consistent for violent crimes than for less serious crimes. Data collected counts juveniles by age or by race, but age and race cannot be compared. Race is reported as White, Black, Indian, and Asian. There is no provision for reporting other races. Hispanic Origin is counted separately and as an ethnicity, not as a race. Oklahoma KIDS COUNT reports juvenile violent crime arrest data on a state and county basis. Several counties reported no juvenile violent crime arrests in the years included in the Oklahoma KIDS COUNT Factbook.
