This tool contains mortality data for Drug Overdoses generally, and Opioid subsets specifically.
"Drug Overdoses" can be from any kind of drug.
“All Opioids” include prescription opioid pain relievers (OPR), heroin, opium, and other/unspecified narcotics.
All Opioids is broken down into 4 mutually exclusive categories: OPR only / Heroin only / Cases where both OPR and Heroin are mentioned / Cases where an opioid is mentioned, but it is not stated what kind. (Opium and Other/Unspecified Narcotics represent ~3% of All Opioids and are not included in the All Opioids subcategories).
The specific ICD10 codes follow:
- A) DRUG OVERDOSES (of any kind, excluding alcohol)
- Where Underlying Cause = X40-X44 (Unintentional), X60-X64 (suicide), X85 (homicide), Y10-Y14 (undetermined), F11.0-F16.9, F-18.0-F19.9.
- B) ALL OPIOIDS SUBSET
- Of Drug Overdoses as listed above, search in any cause for: T40.1 (heroin), T40.2-T40.4 (opioid pain reliever (OPR)), F11 (opioid), F19 (multi-drug), T40.0 (opium), T40.6 (other/unspecified narcotics).
- C) Further breakdown of Opioids:
- c.1: Opioid Pain Reliever (OPR) only (T40.2-.4).
- c.2: Heroin only (T40.1).
- c.3: Both heroin AND OPR (T40.1 and T40.2-.4 coexist).
- c.4: Unknown as to heroin or OPR (F11, F19 with no instance of T40.1 or T40.2-.4).
- T40.0 (opium) and T40.6 (other/unspecified narcotics) are not contained in items c.1 – c.4.
Please note that this definition expands upon definitions used by CDC in that it includes F codes.
- All numbers and rates pertain to the place of residence (not occurrence).
- Maps are used to emphasize the spatial distribution of one or more geographic attributes or variables. This site generates choropleth maps as thematic maps in which the geographies are shaded different colors to represent different magnitudes of a variable.
- The map projection is Lambert Conformal Conic.
- Not Reportable
- At the County level or higher rates (and percents) based on 1-4 events are not reported due to statistical reliability reasons. At sub-county level (Census Tract or County Commission District), rates and percents based on 0-4 are not reported. This assures confidentiality.
- Trendable Maps
- Trendable maps are a series of choropleth maps showing change in spatial
distribution of data in a selected area over selected period of time. Trendable maps share the same
data class breaks which allows easy comparison between each map in the series.
- County to create a map of a selected geography: counties, Public Health District(s) or Perinatal Region(s); or
- Public Health District to create a map of the state by the 18 Public Health Districts; or
- Perinatal Region to create a map of the state by the 6 Perinatal Regions.
- County Commission District or Census Tract to create a map of a selected geography: counties, Public Health District(s) or Perinatal Region(s)
- Census Tracts
- Census Tracts are small, relatively permanent statistical subdivisions of a county or equivalent entity that are updated by local
participants prior to each decennial census.
- Census tracts generally have a population size between 1,200 and 8,000 people. A census tract usually covers a contiguous area;
however, the spatial size of census tracts varies widely depending on the density of settlement. Census tract boundaries are
delineated with the intention of being maintained over a long time so that statistical comparisons can be made from census to census.
Census tracts occasionally are split due to population growth or merged as a result of substantial population decline.
- Census tract boundaries generally follow visible and identifiable features. They may follow nonvisible legal boundaries, such as
minor civil division (MCD) or incorporated place boundaries in some states and situations, to allow for census-tract-to-governmental-unit
relationships where the governmental boundaries tend to remain unchanged between censuses. State and county boundaries always are
census tract boundaries in the standard census geographic hierarchy. Reference Source: U.S. Commerce Department, United States Census Bureau,
accessed July 2011
- A mix of both incorporated places (legal entities) and census designated places or CDPs (statistical entities). An incorporated place is established to provide governmental functions for a concentration of people. Places always nest within a state, but may extend across county and county subdivision boundaries. An incorporated place usually is a city, town, village, or borough, but can have other legal descriptions. CDPs are delineated to provide data for settled concentrations of population that are identifiable by name, but are not legally incorporated under the laws of the state in which they are located. Each dot represents the centroid of the geographical area of the city/town. Click on the dot to get the city or town name. Reference Source: U.S. Census, January 1, 2013.
- County Commission Districts
- For more information, see http://www.accg.org/.The districts are current as of 2008, and were compiled by
Office of Health Indicators for Planning (OHIP) staff in the Georgia Department of Public
Health. History and role: In 1868 the state began creating the position of
county commissioner to administer the general operations of the county. Today
every county has a commissioner; many have a board of commissioners (BOC). As
part of general county operations, the BOC must finance county programs. A BOC
has the power to adopt ordinances, resolutions, or regulations relating to
county property, county affairs, and the operation of local government
- GA House Districts
- Electoral districts from which State Representatives are elected. The Georgia Constitution requires not less than 180 Representatives apportioned by population from representative districts. Layer Source: Georgia Legislative and Congressional Reapportionment Office, 2012.
- Senate Districts
- Electoral districts from which State Senators are elected. The Georgia Constitution limits the number to not more than 56 single member districts. Senate districts are apportioned based on population. Layer Source: Georgia Legislative and Congressional Reapportionment Office, 2012.

- Major roads are a combination of both federal and state highways connecting cities and towns. Click on the line to get the route number. Layer Source: Esri, March 1, 2012.
- Perinatal Regions
- The Perinatal Regions were established by the Department of Public Health in cooperation with the six teaching hospitals located in Atlanta, Albany, Augusta, Columbus, Macon and Savannah. The Regions reflect the hospital referral patterns for high risk pregnant women and newborns. Each of the six hospitals has a Regional Perinatal Center which has contracts with the state and receives funding to care for high risk pregnant women and infants as well as to train staff from other hospitals in perinatal care especially for high risk patients. Reference Source: Georgia Department of Public Health, March 2005.
- ZIP Code
- Established by the U.S. Postal Service for distribution of mail. Zip codes do not generally respect political boundaries or census areas such as tracts. Zip codes usually do not have clearly identifiable boundaries, often serve a continually changing area, are changed periodically to meet postal requirements, and do not cover all land area in the U.S. Layer Source: Esri, June 1, 2013.
Base layers are background information to provide contextual references for local-level maps. They are especially suited for tract-level maps and give real-world reference to maps you create in OASIS. There are three toggle-able (on/off) base layers:
- Demographic Clusters
Demographic Clusters refer to the socioeconomic status classifications created by OHIP, and are at the census block-group level. More information here: https://oasis.state.ga.us/gis/demographiccluster/DemoClusters2011.htm.
- Aerial Photography
Aerial Photography refers to ESRI's World Imagery.
- Street Map
Street Map refers to ESRI's World Street Map with street-level data for North America.
Currently these Base Layers are not available when you Save/Print map.
Data Classification Methods:
- Natural Breaks (Jenks)
This method minimizes within-class variance and maximizes between-class variance
in an iterative series of calculations. This method seeks to partition data into classes
based on natural groups in the data distribution. Natural breaks occur in the
histogram at the low points of valleys. Breaks are assigned in the order of the
size of the valleys, with the largest valley being assigned the first natural

The quantiles method of classification is provided because:
- Data values for each enumeration unit (e.g. county or census tract) are ranked
from lowest to highest.
- The total number of values is divided by the number of classes specified by the
user to determine how many values each class will contain. The object is to
obtain a roughly equal number of data values within each class. For example, if
you have 100 census tracts and the tract data values are to be classed into 5
classes, each class will have 20 values (100/5 = 20).
- In some cases, an equal number of values will not be placed into each class. For
instance, if there are an odd number of enumeration units some classes will have
a larger number of data values than others. If data values for the 159 counties
of Georgia are divided into 4 classes, then some classes might have 39 data
values while others have 40. In addition, identical data values are maintained
within the same classes. Continuing the Georgia county example, if 45 of the
lowest data values are 0, then the lowest class will have 45 data values all
with a value of 0.

- Quantiles classification is one of the simplest methods of classification and is
easy to understand and interpret.
- Classes are usually centered on the median, a measure of central tendency, and
"they group enumeration units above and below the median into classes with equal
frequencies regardless of their values." This makes maps easier to compare with
- Many health-related measures are distributed normally (i.e. a large number of
values falling near the middle of the data range with a smaller number of values
on the low and high ends of the data range) making quantiles classification a
logical classification method.
Ages are presented by Detailed Age Groups, Lifestages and Single Year of Age which is created by the Department of Public Health, OHIP. Also, note that selecting "all ages" will supercede any start and end age selection. Uncheck "all ages" to make an age-specific selection.
- Age-Adjusted Rates
A weighted average of the age-specific mortality rates, where the weights are the proportions of persons in the corresponding age groups of a standard population. The calculation of an Age-Adjusted Rate uses the year 2000 U.S. standard million. Benefit: Controls for differences in age structure so that observed differences in rates across areas such as counties are not due solely to differences in the proportion of people in different age groups in different areas.
- Data Classes
- Also referred to as "class breaks" or
groupings of data.
- Death Rate
- Formula = [Number of Deaths / Population] * 100,000. Rates that use Census Population Estimates in the denominator are unable to be calculated when the selected population is Unknown.
Hispanic or Latino includes persons of Mexican, Puerto Rican, Cuban, South or Central American, or other Spanish culture or origin, regardless of race.
- 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.
- An age year grouping methodology based upon predictable mortality. Georgia uses the following Lifestages: <1 Infancy, 1-4 Early Childhood, 5-12 Later Childhood, 13-19 Adolescence, 20-29 Early Adulthood, 30-44 Young Adulthood, 45-59 Middle Adulthood, 60-74 Late Adulthood, and 75+ Older Adulthood. The highest value for age is 120 years.
- Percent of Death by Cause
- The percent of deaths from a selected cause(s) in selected geography(ies) is of all deaths in the selected geography(ies). If a cause is not selected the user will be prompted to select a cause.
- Formula = [Number of cause-specific deaths in the selected geography(ies) / Number of deaths in the selected geography(ies)] * 100
