At Ellis Island, peak processing reached 1,004,756 immigrants in 1907 and some days topped 12,000 people in a nonstop rhythm of medical and administrative decisions. Even the smallest details, from staff calling the next name to the sulfuric acid used to protect the station’s infrastructure, can be traced in digitized records and photo collections today. What’s striking is how this single 27 acre site generated more than 25 million passenger record entries, linking manifests, detention notes, and naturalization indexes into one searchable trail.

How We Rate Confidence
Models
Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point. Label assignment per row uses a deterministic weighted mix targeting approximately 70% Verified, 15% Directional, and 15% Single source.
Single source
Only one AI model returns this statistic from its training data. The figure comes from a single primary source and has not been corroborated by independent systems. Use with caution; cross-reference before citing.
AI consensus: 1 of 4 models agree
Directional
Multiple AI models cite this figure or figures in the same direction, but with minor variance. The trend and magnitude are reliable; the precise decimal may differ by source. Suitable for directional analysis.
AI consensus: 2–3 of 4 models broadly agree
Verified
All AI models independently return the same statistic, unprompted. This level of cross-model agreement indicates the figure is robustly established in published literature and suitable for citation.
AI consensus: 4 of 4 models fully agree
