This data visualization presents county-level provisional counts for drug overdose deaths based on a current flow of mortality data in the National Vital Statistics System. County-level provisional counts include deaths occurring within the 50 states and the District of Columbia, as of the date specified and may not include all deaths that occurred during a given time period. Provisional counts are often incomplete and causes of death may be pending investigation resulting in an underestimate relative to final counts (see Technical Notes). The provisional data presented on the dashboard below include reported 12 month-ending provisional counts of death due to drug overdose by the decedent’s county of residence and the month in which death occurred. Percentages of deaths with a cause of death pending further investigation and a note on historical completeness (e.g. if the percent completeness was under 90% after 6 months) are included to aid in interpretation of provisional data as these measures are related to the accuracy of provisional counts (see Technical Notes). Counts between 1-9 are suppressed in accordance with NCHS confidentiality standards. Provisional data presented on this page will be updated on a quarterly basis as additional records are received. Technical Notes Nature and Sources of Data Provisional drug overdose death counts are based on death records received and processed by the National Center for Health Statistics (NCHS) as of a specified cutoff date. The cutoff date is generally the first Sunday of each month. National provisional estimates include deaths occurring within the 50 states and the District of Columbia. NCHS receives the death records from the state vital registration offices through the Vital Statistics Cooperative Program (VSCP). The timeliness of provisional mortality surveillance data in the National Vital Statistics System (NVSS) database varies by cause of death and jurisdiction in which the death occurred. The lag time (i.e., the time between when the death occurred and when the data are available for analysis) is longer for drug overdose deaths compared with other causes of death due to the time often needed to investigate these deaths (1). Thus, provisional estimates of drug overdose deaths are reported 6 months after the date of death. Provisional death counts presented in this data visualization are for “12 month-ending periods,” defined as the number of deaths occurring in the 12 month period ending in the month indicated. For example, the 12 month-ending period in June 2020 would include deaths occurring from July 1, 2019 through June 30, 2020. The 12 month-ending period counts include all seasons of the year and are insensitive to reporting variations by seasonality. These provisional counts of drug overdose deaths and related data quality metrics are provided for public health surveillance and monitoring of emerging trends. Provisional drug overdose death data are often incomplete, and the degree of completeness varies by jurisdiction and 12 month-ending period. Consequently, the numbers of drug overdose deaths are underestimated based on provisional data relative to final data and are subject to random variation. Cause of Death Classification and Definition of Drug Deaths Mortality statistics are compiled in accordance with the World Health Organizations (WHO) regulations specifying that WHO member nations classify and code causes of death with the current revision of the International Statistical Classification of Diseases and Related Health Problems (ICD). ICD provides the basic guidance used in virtually all countries to code and classify causes of death. It provides not only disease, injury, and poisoning categories but also the rules used to select the single underlying cause of death for tabulation from the several diagnoses that may be reported on a single death certificate, as well as definitions, tabulation lists, the format of the death certificate, and regul

A. SUMMARY This dataset includes unintentional drug overdose death rates by race/ethnicity by year. This dataset is created using data from the California Electronic Death Registration System (CA-EDRS) via the Vital Records Business Intelligence System (VRBIS). Substance-related deaths are identified by reviewing the cause of death. Deaths caused by opioids, methamphetamine, and cocaine are included. Homicides and suicides are excluded. Ethnic and racial groups with fewer than 10 events are not tallied separately for privacy reasons but are included in the “all races” total.

Unintentional drug overdose death rates are calculated by dividing the total number of overdose deaths by race/ethnicity by the total population size for that demographic group and year and then multiplying by 100,000. The total population size is based on estimates from the US Census Bureau County Population Characteristics for San Francisco, 2022 Vintage by age, sex, race, and Hispanic origin.

These data differ from the data shared in the Preliminary Unintentional Drug Overdose Death by Year dataset since this dataset uses finalized counts of overdose deaths associated with cocaine, methamphetamine, and opioids only.

B. HOW THE DATASET IS CREATED This dataset is created by copying data from the Annual Substance Use Trends in San Francisco report from the San Francisco Department of Public Health Center on Substance Use and Health.

C. UPDATE PROCESS This dataset will be updated annually, typically at the end of the year.

• 12/16/2024 - Updated with 2023 data. Asian/Pacific Islander race/ethnicity group was changed to Asian.
• 12/16/2024 - Past year totals by race/ethnicity were revised after obtaining accurate race/ethnicity for some decedents that were previously marked as “unknown” race/ethnicity.

This dataset includes the count and rate per 100,000 Virginia residents for all-drug overdose deaths among Virginia residents by year and by city/county of the decedent. City/county localities are assigned using the patient's residence at time of death. Data set includes all-drug overdose death counts and rates for years 2018 through the most recent data year available. When data set is downloaded, the years will be sorted in ascending order, meaning that the earliest year will be at the top. To see data for the most recent year, please scroll down to the bottom of the data set.

NOTE: The cumulative Fatal Accidental Overdoses resource (the first table below) has been modified to address a number of issues, including (but not limited to) duplication of many records. Fatal accidental overdose incidents in Allegheny County, denoting age, gender, race, drugs present, zip code of incident and zip code of residence. Zip code of incident is where the Office of the Medical Examiner received the body, not necessarily where the overdose occurred. Data includes closed cases only and the previous calendar year data will be updated monthly until the close of the current calendar year. For example, the 2014 resource will be updated monthly until December 2015. If you are looking for the old yearly files they have been archived and compressed and are available below as a zip file.

A. SUMMARY This dataset comes from the San Francisco Emergency Medical Services Agency and includes all opioid overdose-related 911 calls responded to by emergency medical services (ambulances). The purpose of this dataset is to show how many opioid overdose-related 911 calls the San Francisco Fire Department and other ambulance companies respond to each week. This dataset is based on ambulance patient care records and not 911 calls for service data.

B. HOW THE DATASET IS CREATED The San Francisco Fire Department and other ambulance companies send electronic patient care reports to the California Emergency Medical Services Agency for all 911 calls they respond to. The San Francisco Emergency Medical Services Agency (SF EMSA) has access to the state database that includes all reports for 911 calls in San Francisco County. In order to identify overdose-related calls that resulted in an emergency medical service (or ambulance) response, SF EMSA filters the patient care reports based on set criteria used in other jurisdictions called The Rhode Island Criteria. These criteria filter calls to only include those calls where EMS documented that an opioid overdose was involved and/or naloxone (Narcan) was administered. Calls that do not involve an opioid overdose are filtered out of the dataset. Calls that result in a patient death on scene are also filtered out of the dataset.

This dataset is created by copying the total number of calls each week when the state makes this data available.

C. UPDATE PROCESS Data is generally available with a 24-hour lag on a weekly frequency but the exact lag and update frequency is based on when the State makes this data available.

D. HOW TO USE THIS DATASET This dataset includes the total number of calls a week. The week starts on a Sunday and ends on the following Saturday.

This dataset will not match the Fire Department Calls for Service dataset, as this dataset has been filtered to include only opioid overdose-related 911 calls based on electronic patient care report data. Additionally, the Fire Department Calls for Service data are primarily based on 911 call data (i.e. calls triaged and recorded by San Francisco’s 911 call center) and not the finalized electronic patient care reports recorded by Fire Department paramedics.
