Environmental Data





























An abrupt onset. Acute often connotes an illness or disease that is of short duration, rapidly progressive, and in need of urgent care. Acute is a measure of the time scale of a disease and is in contrast to “chronic."

Adjusted Rate

Adjusted rate means to have been statistically modified to eliminate the effect of different distributions in the different populations. This allows health measures such as rates of diseases and deaths to be compared between several communities with different groups. The most common factor used to adjust rates is age; other factors can also be used, such as race or gender.

Adverse Health Effect

A harmful or abnormal result. It may be caused by administration of a medication or by exposure to a chemical and be indicated by an untoward result such as by illness or death.

Aggregate Data

Data created from individual-level records that have been combined for statistical or analytical purposes.

Aggregated Rate

An aggregated rate is calculated by summing or combining multiple data elements. The practice of using aggregated data is sometimes done to increase statistical power when the amount of data may be limited. It may also be used when displaying the data element individually could potentially compromise confidentiality or provide identifying information on a specific demographic or geography. For example, if a county had a specific health condition with only one case for a specific race or gender, that rate would be aggregated by all races and/or genders before being displayed. A rolling rate is another example of an aggregated rate. Rolling rates are calculated across a time period that will overlap another time period. For example, data may be cumulated for the time period of 2000 - 2002, 2001 - 2003, and 2002 - 2004. Rolling rates are most often displayed in three, five, and ten-year intervals. Aggregated data is sometimes referred to as cumulative or cumulated data.

Air Pollution

The presence in or introduction into the air of a substance, which has harmful or poisonous effects.

Air Quality Index

Air Quality Index (AQI) is a number used by government agencies to communicate to the public how polluted the air currently is or how polluted it is forecast to become. As the AQI increases, an increasingly large percentage of the population is likely to experience increasingly severe adverse health effects.

Ambient Air

Amputation is the removal of part or all of a body part that is enclosed by skin. It is typically performed to prevent the spread of gangrene as a complication of frostbite, injury, diabetes, arteriosclerosis, or any other illness that impairs blood circulation. It is also performed to prevent the spread of bone cancer and to curtail loss of blood and infection in a person who has suffered severe, irreparable damage to a limb. When performing an amputation, surgeons generally cut above the diseased or injured area so that a portion of healthy tissue remains to cushion bone. Sometimes the location of a cut may depend in part on its suitability to be fitted with an artificial limb, or prosthesis.

Confidence Intervals

Confidence Intervals are a range around a value that conveys how reliable and stable the value is. In general, the smaller the confidence interval range is the more reliable and stable the value will be. For example, a 95% confidence interval can be thought of as a range of values or interval that contains the “true value” 95% of the time. If the analysis were conducted 100 times, 95 of those times the final value would fall within the range and five of those times, the final value would fall either higher or lower than the range. Confidence intervals are sometimes referred to as “margins of error.”

Of the six pollutants, particulate matter and ozone are the most widespread health threats. The Environmental Protection Agency calls these pollutants "criteria" air pollutants because it regulates them by developing human health-based and/or environmentally based criteria (science-based guidelines) for setting permissible levels.

Particulate Matter

Also known as particle pollution or PM, particulate matter is a complex mixture of extremely small particles and liquid droplets. Particle pollution is made up of a number of components, including acids (such as nitrates and sulfates), organic chemicals, metals, and soil or dust particles. The size of particles is directly linked to their potential for causing health problems.

Once inhaled, these particles can affect the heart and lungs and cause serious health effects. EPA groups particle pollution into two categories:
