There is a file on your address. Not one file. Several. They exist in separate federal databases, maintained by separate agencies, updated on separate schedules. They contain every reported crime within a mile of your front door, every fatal car crash on every nearby road going back to 1975, your property's designated flood zone, every toxic release facility within proximity, every registered sex offender within a defined radius — name, address, offense, tier classification. All of it is public record. None of it required a warrant. You were never notified it existed.

The problem has never been that the data does not exist. The problem is that no one handed it to you in one place.

The Databases. What Is in Each One.

Federal Bureau of Investigation
FBI Crime Data Explorer
Every reported crime, by agency, by year, going back decades. Offense type, date, location, outcome. Searchable by jurisdiction. Publicly accessible. The majority of Americans have never opened it. The data is voluntary agency submission — which means it is incomplete — but what is there represents the most granular federal crime record available to the public without a court order.

Federal Emergency Management Agency
FEMA National Flood Hazard Layer (NFHL)
Every parcel in the United States carries a flood zone designation. FEMA's National Flood Hazard Layer maps them. The maps contain known errors. First Street Foundation found 145,000 homes in Houston alone that sit in flood zones not accurately reflected on current FEMA maps. The federal data understates risk. The underlying reality is worse than what the map shows.

145,000 homes in Houston, Texas alone sit in flood zones that are not accurately shown on FEMA's official National Flood Hazard Layer maps. The federal record understates flood risk by a documented margin. First Street Foundation flood risk analysis — https://firststreet.org
National Highway Traffic Safety Administration
NHTSA Fatality Analysis Reporting System (FARS)
Every fatal motor vehicle crash on every road in the United States, going back to 1975. Location coordinates, time of day, contributing factors, vehicle type, driver condition. Fifty years of death records, geocoded to the road segment. The intersection two blocks from your house — if someone has died there, it is in FARS. The data is there. It has always been there.

Environmental Protection Agency
EPA EnviroFacts / EJScreen
Every Superfund site. Every facility that has ever reported a toxic chemical release under the Toxics Release Inventory. Every brownfield. Every lead risk area. All geocoded. All cross-referenceable to a street address. EJScreen adds a demographic overlay — it was built to document environmental injustice, but the underlying data is a complete catalog of industrial contamination events tied to physical locations. Public. Downloadable. Mostly unread.

National Oceanic and Atmospheric Administration
NOAA Storm Events Database
Every tornado, hurricane, flood, severe thunderstorm, and extreme weather event on record. Going back more than 60 years. Location, intensity, fatalities, property damage. The same geographic areas appear in this record repeatedly. A neighborhood that flooded in 1978, 1992, 2004, and 2017 has a documented pattern. That pattern is in the database. It was always in the database.
https://www.ncdc.noaa.gov/stormevents
State Sex Offender Registries / National Registry
Registered Sex Offender Databases
Every registered sex offender in the United States: name, current address, photograph, tier classification, specific offenses. All public record under Megan's Law and the Adam Walsh Act. Tier I through Tier III classification determines registration duration and community notification requirements. The current residential address is updated by law. The data exists at the state level and is aggregated by third-party services including Offenders.io. It is public. It requires no special access.

The Floor Problem

All of the above represents what was reported, what was logged, and what survived the documentation process intact. It is not the full picture. According to the Bureau of Justice Statistics National Crime Victimization Survey, 52 percent of all violent crimes in the United States go unreported to police. The FBI's Crime Data Explorer — the most comprehensive public crime database in existence — is built entirely on reported crimes. It documents, at most, 48 percent of what actually occurred.

52% of all violent crimes go unreported. Every federal crime database — every crime map, every safety score derived from police records — is built on the other 48%. The federal record is a floor, not a ceiling. Bureau of Justice Statistics, National Crime Victimization Survey (NCVS), 2024 — https://bjs.ojp.gov/library/publications/criminal-victimization-2023

This applies to the crime data only. The FARS crash data is close to complete — fatal crashes require a police response and are almost universally documented. NOAA weather events are instrumentally recorded. EPA toxic release reports are legally mandated filings. The flood hazard data has known gaps, as the First Street Foundation analysis demonstrates, but it is not subject to a voluntary reporting problem in the same way crime data is.

The upshot: for environmental, weather, and infrastructure risk, the federal databases are a reasonable representation of reality. For crime, they are a lower bound.

SAMHSA Treatment Facility Density

The Substance Abuse and Mental Health Services Administration maintains a public database of every licensed substance use treatment facility in the United States. Address, capacity, treatment modality, funding type — all public. The database was built for healthcare planning. Its secondary implication — that facility density in a given area correlates with the intensity of drug activity in the surrounding geography — is not a conclusion SAMHSA draws. It is a conclusion the data supports. The information is there regardless of what label it carries.

Substance Abuse and Mental Health Services Administration
SAMHSA Treatment Facility Locator (N-SSATS)
Every licensed substance use treatment facility in the U.S. — address, capacity, services offered. Built for healthcare resource planning. Geocoded. Public. Downloadable. The geographic concentration of treatment facilities is a data point. What you do with it is a separate question.

What Has Not Been Done

Every database listed above is publicly accessible. None of them talk to each other. None of them were designed to answer the question: what is the composite risk profile of this specific address. They were built for policy analysis, infrastructure planning, law enforcement reporting, and regulatory compliance. Assembling them into a single address-level profile requires pulling from seven separate systems, normalizing geospatial data across incompatible formats, reconciling different update cadences, and presenting the result in a form that is usable by someone who is not a federal data analyst.

That is the only thing SafeScore does. The underlying data is federal, primary, and public. The work is the assembly. The output is what exists in those databases — rendered for a single address, without smoothing, without aggregation to the zip code level, without the layer of reassurance that neighborhood safety apps add because their business model depends on people not being unsettled.

The data on your address has always existed. You were just never given access to all of it in the same place.
