Whatcom County crime rates and
jail bookings, 2020–2025.

Washington State's 2024 crime data, drawn from the National Incident-Based Reporting System (NIBRS) - shows that reported crimes in Whatcom County declined across nearly every major category between 2023 and 2024, even as jail bookings increased by 21%. Understanding what NIBRS measures, and what it doesn't, is essential to an honest public conversation about incarceration and public safety.

Module 1, Understanding the Data

What Is NIBRS, and Why Does It Matter?

NIBRS, the National Incident-Based Reporting System, is the modern standard for crime data collection in the United States. Washington State reports through NIBRS via the Washington Association of Sheriffs and Police Chiefs (WASPC). Understanding how NIBRS works is essential to reading crime data accurately, and to understanding the difference between crime trends and incarceration trends.

The core distinction
NIBRS measures reported crimes, not arrests, not bookings, not incarceration.
A person can be booked into jail without a NIBRS crime being reported. Conversely, many reported crimes result in no arrest. The gap between crime trends and booking trends is not a contradiction, it is a signal about how policy shapes incarceration independently of crime levels.
🔴
Group A: Crimes Against Persons
Offenses where people are the direct target of criminal acts. Measured by number of victims, not incidents. This is the category most closely tied to public safety as most people understand it.
Murder Rape Aggravated Assault Simple Assault Intimidation Robbery Kidnapping Sex Offenses Human Trafficking No-Contact Order Viol.
🔵
Group A: Crimes Against Property
Offenses where property is the primary target. Measured by number of offenses. This is the largest category in Washington State by volume, driven heavily by larceny/theft.
Burglary Larceny/Theft Motor Vehicle Theft Arson Destruction of Property Fraud Counterfeiting Embezzlement Stolen Property Extortion
🟣
Group A: Crimes Against Society
Offenses against the social order or public welfare where there may be no direct victim. This category includes drug violations, making it particularly relevant to interpreting booking trends after Washington's SB 5536.
Drug/Narcotic Violations Drug Equipment Violations Weapon Law Violations Prostitution Pornography Gambling Animal Cruelty
Group B offenses are lower-level offenses tracked by arrest only, not by incident report. These include DUI, disorderly conduct, trespass, liquor law violations, and curfew violations. In Whatcom County, DUI is a dominant booking category, but it appears in both NIBRS Group B (tracked by arrest) and in jail booking data. This is one of many ways crime data and booking data can diverge.

Possible arrest
Suspect may or may not be arrested. An arrest can happen even without a NIBRS crime report (e.g., warrant arrests, Department of Corrections (DOC) detainers).

Possible booking
Arrest may result in a jail booking, or not, for cite-and-release. A booking is NOT the same as a crime being reported.
What NIBRS Counts, vs. What It Misses
Limitations every reader should understand
⚠
Only reported crimes are counted. Many crimes, especially domestic violence, sexual assault, and drug use, go unreported. NIBRS captures what agencies receive, not what occurs.
⚠
Only participating agencies are included. In 2024, 198 WA agencies reported two consecutive years. Lummi Nation tribal police data may be counted separately or differently.
ℹ
Warrant arrests are not NIBRS crime reports. Failure to Appear (FTA) warrant bookings (1,241 in 2025) do not appear in NIBRS crime statistics because they involve enforcement of prior court orders rather than new reported incidents.
ℹ
DOC detainer bookings are NOT a crime report. The 237 DOC detainer bookings in 2025 reflect state supervision policy, not new crimes committed or reported in Whatcom County.
✓
Crime rates are population-adjusted. NIBRS data is expressed as offenses per 1,000 residents, allowing apples-to-apples comparison across jurisdictions of different sizes.
Washington State transitioned fully to NIBRS in 2021, replacing the older UCR (Uniform Crime Reporting) summary system. NIBRS is more detailed, capturing incident-level data including victim/offender relationships, location, weapon type, and circumstances, but it also means pre-2021 data may not be directly comparable across all offense categories. The 2024 WASPC report uses consistent NIBRS methodology for 2020–2024.
Module 2, Washington State Context

Statewide Crime Trends, 2020–2024

Washington State crime data from NIBRS shows that most major offense categories peaked in 2021–2022 and have declined significantly since. This statewide context matters for interpreting Whatcom County trends: local crime is declining as part of a broader statewide pattern, not rising.

Module 3, Whatcom County Deep Dive

Crime by Offense Type: Whatcom County Jurisdictions

The 2024 NIBRS data provides detailed offense-level statistics for each Whatcom County law enforcement agency. Two jurisdictions account for the vast majority of reported crime: Bellingham PD (pop. 97,270) and the Whatcom County Sheriff's Office (pop. 94,465, serving unincorporated areas). Both showed significant declines in 2024.

Notable in Bellingham: Larceny/theft fell 36% (3,483 → 3,286 offenses, then a further revision). Burglary fell 26%. Destruction of property fell 33%. Aggravated assault rose 12.4%, the only significant persons category to increase. Drug/narcotic violations rose 90%, consistent with SB 5536 effects. Violation of no-contact orders rose 87%, reflecting both increased enforcement and case backlogs.
Module 4, City-by-City Comparison

Crime Rates Across Whatcom County Jurisdictions

Crime rates per 1,000 residents allow direct comparison across jurisdictions of different sizes. These numbers come from official 2024 NIBRS submissions and reflect only Group A reported offenses for each jurisdiction.

Sumas PD 1,835 8 24 +200% 13.1 50.0% 7
WWU Police - 327 350 +7.0% - 4.3% 6
Reading rate differences: Bellingham's high rate (85.3 per 1,000) reflects both its urban concentration and the fact that Bellingham serves as the regional hub, drawing in commercial activity, transient populations, and service utilization from across the county. The WCSO's low rate (19.6) reflects the predominantly rural, lower-density character of unincorporated Whatcom County. These rates are not directly comparable as indicators of "safety" without accounting for daytime population, service area, and reporting practices.
Module 5, Trends in Context

The Divergence: Crime Down, Bookings Up

This section presents the crime trend data and booking data together so readers can examine the divergence directly. Three specific categories, warrant bookings, DOC detainer bookings, and drug possession charges following SB 5536, account for the majority of the 2023–2025 booking increase. NIBRS-reported crimes over the same period declined in major Whatcom County jurisdictions.

The key divergence
Whatcom County's 2023–2025 booking increase occurred while NIBRS-reported crimes declined in the major Whatcom County jurisdictions.
Three categories account for most of the booking increase: warrant accumulation (FTA bookings), DOC detainer bookings following state supervision policy changes, and drug possession charges following SB 5536. NIBRS crime reports declined over the same period. What these patterns mean for facility sizing and program investment is a question the planning process addresses with this data as one input.

Source: WCSO Public Booking Data 2023–2025. Analysis: Chuckanut Health Foundation. Three categories, FTA warrant accumulation, DOC detainer bookings following state supervision policy changes, and SB 5536 drug possession charges, account for approximately 76–83% of the 2023–2025 increase. DUI bookings remained relatively stable over the same period.

🔴
Violent Felony Bookings: Below 2019 Levels
Per Washington State University (WSU) analysis and WCSO data, violent felony bookings in Whatcom County remain below pre-pandemic 2019 levels. The booking surge is not a violent crime phenomenon. NIBRS aggravated assault in Bellingham rose 12% in 2024, but from a lower base, and the county's total serious violent felony booking count was minimal relative to the overall surge.
🔵
Property Crime: Down, Not Up
Larceny/theft fell 36% in Bellingham between 2023 and 2024. Motor vehicle theft fell 37%. Burglary fell 26%. These are the crime categories most associated with community safety concerns. Their decline over this period is relevant context for understanding the relationship between crime trends and booking trends.
🟣
Drug Charges: SB 5536 and the Booking Trend
Drug/narcotic violations in Bellingham rose 90% in 2024, and drug-related bookings rose sharply in 2025. This reflects Washington's SB 5536 (2023), which re-criminalized drug possession after the Blake decision. This reflects a statutory change, SB 5536 restored criminal penalties that had been removed by the Blake decision, rather than an underlying shift in community drug use patterns.
Methodological note on combining data sources: NIBRS crime data and WCSO booking data measure different things and cannot be directly combined into a single rate. NIBRS measures reported offenses per 1,000 residents. Booking data counts jail admissions, which includes non-crime categories (warrants, DOC holds, Electronic Home Detention (EHD) check-ins). The comparison above is directional, illustrating the divergence in trend, and should not be interpreted as a precise numerical relationship between crimes and bookings.
