This statistic shows the eligible voters who voted in general elections, which we define as November general elections that occur statewide on even-numbered years. It excludes special or primary elections.

The percentage was calculated by dividing the total number of people who voted by the total population ages 18 and older (citizen voting age). The population is found using the most recent Census estimates (e.g. 2023 Census population for 2024 election data).

Number of live births to Tulsa County females aged 15 to 19 per 1,000 females in the same age group. The rate is reported by single calendar years.

Birth data (ZIP code level): Calculated by the Tulsa Health Department (THD) using raw data files from the Oklahoma State Department of Health (OSDH), Center for Health Statistics, Health Care Information.

Denominator (population of females aged 15–19): U.S. Census Bureau, American Community Survey 5-Year Estimates.

This metric shows births to mothers who either received no prenatal care or began care after the first trimester (after 12 weeks of gestation). It is presented as a percentage of all live births, reported by single calendar years.

Total births at the ZIP code level were calculated by the Tulsa Health Department (THD) using raw data files from the Oklahoma State Department of Health (OSDH), Center for Health Statistics, Health Care Information.

This metric shows infants weighing less than 2,500 grams (5 pounds, 8 ounces) at birth. This statistic is expressed as a percentage of all live births to Tulsa County mothers, reported by single calendar years.

Infants born with low birth weight are at higher risk for health complications such as developmental delays and respiratory problems. Factors like smoking, alcohol use, poor nutrition, stress, domestic violence, and environmental exposures can increase the risk. Early and regular prenatal care plays a critical role in helping prevent low birth weight and improving health outcomes.

Preterm birth is a significant public health concern as it is a leading cause of infant mortality and contributes to long-term health challenges, including an increased risk of illness and disability throughout life. Factors such as maternal age, race, socioeconomic status, infections, previous preterm births, multiple pregnancies, and lifestyle choices like tobacco or alcohol use can increase the likelihood of a preterm delivery. Monitoring the prevalence of preterm births helps identify at-risk populations and can inform targeted interventions to improve maternal and child health outcomes.

A person infected with HIV is diagnosed with AIDS when they develop an AIDS-defining condition or meet certain laboratory criteria, such as a CD4 lymphocyte count below 200 cells/mm³ or a CD4 percentage of total lymphocytes below 14%. It’s important to note that a positive HIV test does not mean the person has AIDS.

This statistic is expressed as a rate per 100,000 population.

This indicator includes the combined number of reported cases of sexually transmitted infections (STIs), such as chlamydia, gonorrhea, and syphilis, based on standard case definitions. These infections are spread primarily through sexual contact and can cause a range of health issues if left untreated. Tracking the combined total helps illustrate the overall burden of STIs in the community and supports efforts in prevention and intervention.

This statistic is expressed as a rate per 100,000 population, based on reported cases in a single year.

Syphilis is a sexually transmitted infection (STI) caused by the bacterium Treponema pallidum. It is transmitted through direct contact with a syphilis sore, known as a chancre. The primary stage typically begins 2–6 weeks after exposure with the appearance of a chancre, which may heal without treatment. However, untreated syphilis can progress to the secondary stage, often marked by a body-wide rash, and then to latent and late stages. Late-stage syphilis can lead to severe health complications, including organ damage, paralysis, blindness, dementia, and even death. In pregnant women, syphilis can cause miscarriage, premature birth, stillbirth, or serious complications for the newborn such as deafness, seizures, or cataracts.

This statistic is expressed as a rate per 100,000 population, based on reported cases in a single year. Zip code level data calculations were performed by the Tulsa Health Department (THD) using raw data from the Oklahoma State Department of Health (OSDH), Center for Health Statistics (CHS), Health Care Information (HCI), with population estimates from the U.S. Census Bureau (census.gov).
