Population Records: Open Questions

NAMED GAPS, WITH THEIR SETTLERS

• County foreign-born, 1880–1970. Not verified. Settlers: the county nativity tables of each census's population volume (Tenth Census 1880, Vol. I; Twelfth 1900, Vol. I; Thirteenth 1910, Vol. III; Fourteenth 1920, Vol. III; Fifteenth 1930, Vol. III; 1960, Vol. I, Part 16; 1970, Vol.
• Township 1890–1920 and 1980 at volume strength. Carried at the State Data Center compilation's strength in the township article. Settlers: the Eleventh Census Vol. I MCD table; the 1900/1910/1920 "Number of Inhabitants" volumes' Indiana MCD tables; the 1980 Census, Vol. I, Ch. A, Pt. 16, Table 4.
• The 1880 county discrepancy of sixty. Table II's 33,178 against the Table III subdivision sum of 33,118 stands unexplained inside the volume itself; both print in the township article. No settler beyond the volume has been identified; the discrepancy is carried as found.
• The 1850 Mishawaka line (1,412). Derived from the table's own columns and forced by the county total — the scan's figures for that line are partially garbled in the text layer — and flagged as derived wherever it is used; the four township figures and the county total are unaffected. Settler: a clean page-image read of the Seventh Census, Table II, p. 774.
• IBRC county projections for 2045 and 2050 as figures. Published only behind STATS Indiana's interactive tables; the printable profile ends at 2040 and the 2050 endpoint is stated qualitatively by the Center. The figures are therefore not printed as figures.
• GAP-O1-10 — apportionment. The division of Penn's growth among the town, Mishawaka's annexations and the unincorporated remainder stands unapportioned. Settlers: the census volumes' boundary footnotes read whole across the century, with the two cities' annexation ordinances (the check of CPH-2-16's town footnotes for 2000–2010 named in the boundary article is the first step).
• Images located, none pulled. No image is used in this section.
