U.S. Ethnic Composition Trends (1861-1987) | Historical Demographic Data #1397368 (License: Personal Use)

The chart displays five time points-1861, 1891, 1947, 1978, and 1987-with each bar segmented by ethnicity: German (maroon), Italian (green), Irish (yellow), Scottish (orange), and English (navy). English ancestry consistently forms the largest segment until 1947, after which German and Irish contributions rise significantly, reflecting late-19th and early-20th century immigration patterns. Post-1947, Italian representation grows notably, especially by 1978 and 1987, while German and Scottish shares decline slightly.
