Executive summary

There are no reliable, authoritative counts in the supplied reporting that answer, for calendar year 2024, how many U.S. citizens were killed by people classified as “illegal aliens” versus how many were killed by a spouse; available sources emphasize comparative rates and trends rather than a single national tally [1] [2] [3]. Major studies and government summaries in the record show undocumented immigrants have lower homicide and violent‑crime rates than native‑born Americans [2] [3], while the supplied materials do not contain a national figure for intimate‑partner homicides in 2024 nor a matched dataset that isolates killings of U.S. citizens by noncitizens for that year [1] [4].

1. The question being asked and the data gap it exposes

The user asks for two discrete, countable quantities — U.S. citizens killed by “illegal aliens” in 2024 and U.S. citizens killed by a spouse — but the supplied reporting includes policy and research summaries, not a compiled, nationwide event‑level census cross‑referencing victim citizenship, perpetrator immigration status, relationship between victim and offender, and calendar year 2024; that combination of fields is not present in these sources, so the precise comparative counts cannot be produced from the materials provided [1] [4].

2. What the supplied sources can reliably say about homicide and immigration

Multiple peer‑reviewed and government‑funded analyses in the material show that undocumented immigrants, as a group, have homicide arrest and conviction rates that are lower than those of native‑born U.S. citizens — for example, NIJ‑funded analyses and Texas arrest studies find undocumented people are arrested for violent crimes, including homicide, at less than half the rate of U.S.‑born citizens during examined periods [2] [3], and broad reviews conclude that undocumented immigration does not increase violent crime [5]. These findings undermine simple claims that large numbers of homicides in the U.S. are attributable proportionally to people in the country without authorization, but they do not provide a single‑year absolute count of victims who were U.S. citizens and were killed by perpetrators later identified as “illegal aliens” [2] [3] [5].

3. What the supplied sources say about government enforcement tallies and their framing

U.S. Customs and Border Protection produces Criminal Alien Statistics for Fiscal Year 2024 that summarize enforcement and conviction records for apprehended noncitizens, but CBP’s dataset is framed around enforcement encounters and the criminal history of apprehended individuals rather than a victim‑centered national counting of homicides by perpetrator immigration status for calendar year 2024; relying on CBP alone risks conflating enforcement volume and public messaging with a population‑level incidence measure [1]. That framing suggests an implicit agenda: enforcement agencies report apprehension and conviction details to justify border and removal activities, which is why independent academic analyses are necessary to assess comparative rates [1] [3].

4. The spouse‑killing side of the ledger: missing or non‑matching data in the supplied reporting

The reporting provided includes domestic‑violence context and general homicide research, but does not deliver a national 2024 count of homicides where the perpetrator was a spouse or intimate partner [4] [6]. Intimate‑partner homicide statistics are typically compiled by the CDC, the FBI’s National Incident‑Based Reporting System or the National Violent Death Reporting System (NVDRS), none of which are present with 2024 national tallies in the supplied material; therefore it is not possible from these sources to state how many U.S. citizens were killed by a spouse in 2024 [4].

5. How to get the exact numbers and how to interpret them if found

To obtain the precise 2024 counts requested, researchers should consult event‑level databases that record victim relationship and perpetrator nativity/status: NVDRS and CDC/CDC‑WISQARS for victimization context and the FBI’s homicide/NIBRS datasets for offender‑victim relationship, cross‑referenced with immigration status records from law‑enforcement or DHS/ICE where available; be aware that immigration status is imperfectly recorded and that enforcement datasets (e.g., CBP criminal‑alien stats) reflect apprehension and conviction populations rather than exhaustive, victim‑based national tallies [1] [4]. Where independent academic studies exist, they should be preferred for rate comparisons because they control for population denominators and reporting biases that raw enforcement counts do not [2] [3].

6. Bottom line and caveats

The supplied reporting supports two firm conclusions: first, scholarly and NIJ‑funded work finds undocumented immigrants commit homicide at lower rates than U.S.‑born citizens [2] [3]; second, the specific numeric comparison the user requested — exact counts of U.S. citizens killed by “illegal aliens” in 2024 versus killed by a spouse — cannot be answered from the documents provided because those documents do not contain a national, matched count for 2024 that includes both perpetrator immigration status and perpetrator‑victim relationship [1] [4]. Any future reporting that supplies an absolute count should be scrutinized for methodology (how immigration status was determined, whether victims were limited to citizens, and whether counts represent arrests, convictions, or known incidents).
