Ethical Tech CoLabGBV Patterns

How this was built, and what it cannot claim

Every number on this site has a public source. This page says where each one comes from, how the project will code the case-level data, and the limits a careful reader, or a hostile one, should hold against it.

Scope

Region, period and definitions.

The study region is New York State, with New York City broken out because the city and state publish on different systems that do not reconcile. National and global figures appear only as context for the state. The core period is 2023 to 2024 for official statistics, because those are the latest complete years, and 2016 to 2026 for case-level data, because Women Count USA's coverage is most complete from the year it began.

Femicide is used in the UNODC and UN Women sense: the intentional killing of a woman or girl because of her gender, operationalised in their estimate as killing by an intimate partner or family member. Women Count USA uses a broader rule, any woman or girl killed by a man or boy. New York law has no definition. CATW's proposal is that killings of women in prostitution and sex trafficking be recognised within it. This site keeps the three definitions visibly separate.

Data sources and what each can answer

Official statistics are quoted exactly as published. Nothing is modelled or imputed.

How the case-level data will be coded

The rules below are written down before any aggregation runs, so they can be reviewed by Women Count USA and CATW first.

Access

The fifteen databases are read through the public share links on womencountusa.org using analysis/fetch_wcusa.py. Raw exports stay on the analyst's machine and are never committed. Only coded fields and counts would be published, and only with permission.

Fields read

Date, state, city, her age, her race, relationship, his age, his race, cause of death, location type, case status, keywords, additional details, single or multiple victim, murder-suicide. Names, photographs, narratives, addresses and source links are not read by the coding script.

Groupings

  • Relationship: intimate partner (husband, boyfriend, domestic partner, fiancé, and their ex and estranged forms); family (father, son, brother, grandfather, cousin, caregiver and their step and in-law forms); commercial sexual exploiter; stranger; acquaintance or other known (acquaintance, neighbour, landlord, coworker, classmate, client, service provider, hitman); unknown.
  • Age: under 18, 18 to 24, 25 to 34, 35 to 44, 45 to 54, 55 to 64, 65 and over. Infants recorded in months or weeks are coded as age 0.
  • Sex-trade involvement: true when the relationship is "commercial sexual exploiter" or the additional details include "commercial sexual exploitation / prostitution" or "killed during commercial sex encounter". No free-text matching, so this is a floor, not a count.
  • Cause: firearm, sharp force, asphyxiation, blunt force, other, unknown.

Presentation

Counts below five in any cell are suppressed in public charts. No chart identifies an individual. Maps stop at county level.

Limitations

Ordered by how much they could change a conclusion.

High

Not every case is in the system, and not every case in the system is called femicide

Official counts rely on a reported crime with a recorded relationship. Women Count USA relies on a news story existing. A woman killed in the sex trade can be missing from both: filed as an overdose, an accident, an unknown relationship, or never reported. Any count here is a floor.

High

The region is one state, and its two halves do not add up

New York City and the rest of the state report through different systems. The state's own dashboard warns that the two cannot be combined or compared. Findings for New York do not transfer to other states, and national rates are not a benchmark for the city.

High

Media-sourced data inherits media bias

Cases involving white, young, middle-class victims receive more coverage and so more complete records. Cases involving women in prostitution, undocumented women, Black and Native women and trans women are more likely to be missing or thinly recorded. Demographic patterns from the database partly measure who gets written about.

Medium

Definitions differ across sources

UN estimates count partner and family killings. Women Count USA counts any killing by a man. New York counts domestic violence, not femicide. Numbers from different sources are placed side by side, never summed.

Medium

Rising counts can mean rising reporting

More incident reports, hotline calls or orders of protection can reflect better outreach and trust rather than more violence. Homicide counts are the least affected by this. The hypotheses page treats this as a question, not an assumption.

Medium

The economic figures are illustrative

Lost earnings use a state median, assume work to 65 and apply no discount rate, wage growth or unpaid-work value. Per-victim costs are national and in 2014 dollars. They show scale, not a budget line.

Medium

Small numbers by borough

Borough homicide counts are in the single digits. A change from 3 to 8 is real for those families and statistically fragile. Year-on-year borough comparisons should not be read as trends.

Low

Live databases change

Women Count USA is edited daily. The share links on the patterns page always show the current version, so a figure quoted from it today may differ tomorrow. The methodology records the date of any snapshot used.

Low

Global clock rates are annual averages

The counters spread yearly estimates evenly across seconds. They convey scale, not timing.

Low

Causation is not shown anywhere on this site

Correlations between representation, economic stress, social media and violence are posed as hypotheses. Countries with more women in office are also richer, older democracies; any leadership-impact claim needs that confound addressed before it is made.

Ethics and privacy

Patterns, not profiles.

  • No victim or perpetrator is named on this site. Case-level data is shown only through the owner's own published views.
  • Aggregation of Women Count USA will proceed only with written agreement from Dawn Wilcox and CATW on what may be published.
  • Perpetrator analysis uses age, race and relationship to the victim, never names, consistent with CATW's stated priority.
  • The site carries a content warning on the home page and links to support resources in New York.
  • Code and coding rules are open in the repository so that every figure can be reproduced.
