Investigation and Outcomes Data Source and AnalysisThis report summarizes NVDRS data covering 49 states (all except Florida), the District of Columbia, and Puerto Rico.Analysis subjects included female victims of intimate partner homicide* aged 18 years.Population crude rates (female intimate partner homicide deaths per 100,000 women) were calculated for 2018-2019 and 2020-2021. Selected characteristics of the victim, suspected perpetrator (suspect), and incident were tabulated.Observations were compared between periods using Wilcoxon rank sum and Pearson's chi-square tests as appropriate; p-values <0.05 were considered statistically significant.This activity was reviewed by CDC,
