This Web Query 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) and heroin.

All Opioids can be broken down into 4 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.

The specific ICD10 codes follow:

Please note that this definition expands upon definitions used by CDC in that it includes F codes.

Presentation Information

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.

Mapping Units:

Visible Layers:

Cities/Towns
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.
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.
Hospitals
Hospitals are the non-Federal acute-care inpatient medical facilities in Georgia. Click on the symbol to get the name. Reference Source: Georgia Hospital Assoociation, 2012.
Interstates
Interstates are the freeways that are part of the Interstate Highway System in Georgia. The Interstate Highway System connects major cities within the United States. Click on the line to get the Interstate number. Layer Source: Esri, March 1, 2012.
Major Roads
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:

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 break.
George F. Jenks is considered a pioneer in GIS educational programs. Through an award from the Fund for Advancement of Science, Jenks identified four key objectives for cartographic training. Robert McMaster and Susanna McMaster; A History of Twentieth-Century American Academic Cartography

Definitions:

Age
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.
Ethnicity
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.
Lifestages
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.
Race
Per the Federal Office of Management and Budget, Directive 15 (1997),
