This study tracks the Korku population in Maharashtra across the 1961–2011 censuses using district-by-tribe counts harmonized for boundary changes (e.g., Washim, Palghar, Hingoli, Gondia). We pair descriptive tabulation with four simple tools: a log-linear OLS trend for average annual growth, a chi-square test to compare the 1981 and 2011 spatial mixes, the Herfindahl–Hirschman Index (HHI) for concentration, and decade-wise CAGR. Totals rise from 50,279 to 264,492 (~5.26×). The trend slope implies ~3.46% growth per year (t≈16.7, p<0.001). Amravati remains the dominant hub (≈91% in 2011), while modest increases appear in Akola+Washim, Buldhana, Wardha, Nagpur, and Jalgaon; the 1981–2011 mix differs sharply (χ²≈794, df=6, p<0.001). HHI falls slightly (0.854→0.831), indicating small diffusion but persisting concentration. CAGR is highest in 1971–1981 (~5.6%/yr), slows in 1981–1991 (~2.0%/yr), rebounds in 1991–2001 (~4.1%/yr), and eases in 2001–2011 (~2.2%/yr). Findings provide a clean baseline for planning: prioritize Amravati, monitor emerging fringe districts
