AI on WW I & WW II heroes fro Europe's Freedom... a preliminary study..

 No comprehensive city-by-town casualty table exists (or can be reliably calculated) for every locality in the USA, Canada, Australia, New Zealand, and other nations for WWI and WWII. Official records track national (and sometimes state/provincial or unit) military deaths, not exhaustive hometown tallies for thousands of cities and towns. Individual honor rolls, local memorials, and archives (e.g., U.S. National Archives WWII lists by state/county, Commonwealth War Graves Commission, Australian War Memorial) exist for some places, but compiling or inventing complete per-city figures for all locations would be inaccurate and incomplete. Your example numbers for NYC (2,308 WWI / 4,567 WWII) do not match available historical estimates.

Approximate national military deaths (primarily or including European theaters; figures vary slightly by source due to definitions of battle vs. non-battle, missing, postwar, etc.)These are the best-attested totals from official/historical compilations (Commonwealth War Graves, U.S. DoD/VA-linked sources, Wikipedia summaries of primary data). Focus is on military fatalities from the listed countries; “other foreign nations” is too broad for a single precise list, but major non-European Allies are noted where relevant. Most Canadian, Australian, New Zealand, and many U.S. deaths in these wars occurred in or related to the European (and Mediterranean) theaters.

World War I (1914–1918)

Country	Approx. military deaths	Notes
United States	~116,500–117,000	Official ~116,516 (incl. ~53,400 battle); many disease (esp. flu). U.S. involvement mainly 1917–18, Western Front. web.archive.org
Canada	~61,000–65,000	Commonwealth figures ~64,900 incl. some postwar; CEF dominant. en.wikipedia.org
Australia	~60,000–62,000	~61,900; heavy Western Front + Gallipoli. en.wikipedia.org
New Zealand	~18,000	~18,050; Western Front + Gallipoli. en.wikipedia.org
United Kingdom	~886,000	Included for context (British Empire core).
Other (examples)	India ~74,000; South Africa ~9,500	Colonial contributions under Empire.

World War II (1939–1945)

Country	Approx. military deaths	Notes
United States	~407,000–419,000	~250,000 in European theater (rest largely Pacific). Total incl. all causes. en.wikipedia.org
Canada	~42,000–45,000	Primarily Europe (Italy, NW Europe, Atlantic).
Australia	~39,700–40,500	Significant Europe/Mediterranean + Pacific/Middle East.
New Zealand	~11,700–12,000	Europe (esp. Italy, Greece/Crete) + Pacific.
United Kingdom	~383,700	Core Allied force in Europe.
Other (examples)	South Africa ~11,900; India (British Indian Army) tens of thousands	Varied theaters.

Totals for the four main requested countries (military deaths, approximate ranges):

• WWI: USA + Canada + Australia + NZ ≈ 255,000–262,000.

• WWII: USA + Canada + Australia + NZ ≈ 500,000–517,000 (U.S. Europe portion alone ~250,000).

These men and women served as part of the Allied effort against the Central Powers (WWI) and Axis (WWII). Many are commemorated as having died in the cause of defeating authoritarian aggression in Europe (and elsewhere). Local memorials, cenotaphs, and databases (American Battle Monuments Commission, Commonwealth War Graves Commission, national war memorials) list individuals by name and often unit or burial site; state/county-level U.S. WWII Army/AAF honor lists exist via the National Archives, and some cities have published rolls, but no unified “all cities and towns” spreadsheet covers every place.

City-level examples cannot be exhaustively calculated or listed here because the underlying complete data does not exist in aggregated form. For New York specifically, one detailed source places NYC WWI military fatalities (all branches/causes) around 7,400–7,500; WWII New York State totals were among the highest of any U.S. state (tens of thousands). Similar local research is needed for other cities (e.g., via provincial archives in Canada, state memorials in Australia, or NZ History resources).

If you want national totals expanded, state/provincial breakdowns where available, links to searchable databases (ABMC, CWGC, AWM), or focus on a specific city/region with known local rolls, provide more details and I can help narrow it further with available records. These sacrifices were real and documented at the national and individual levels; inventing city-by-city numbers would not honor that.
