“Analyze Tamil Nadu’s economic growth under every ruling government from the 1950s to 2026. For each government, identify the ruling party and tenure, and compare the state’s GSDP at the beginning and end of its tenure, real GSDP growth, CAGR, and per-capita GSDP growth. Rank the governments and ruling parties by economic performance, using inflation-adjusted figures wherever possible. Clearly distinguish between nominal and real growth and cite the underlying government/statistical sources for all figures.”
Twenty administrations and four President’s Rule spells governed Tamil Nadu between April 1952 and 2026. India’s state-income statistics changed concept (net NSDP vs gross GSDP) and constant-price base four times over that span, so no single inflation-adjusted series covers all of it: annual real GSDP growth is solid from 2005-06 onward, while earlier decades rest on published NSDP-based decade averages. All figures in ₹ crore; real · constant price and nominal · current price are labelled throughout.
| Administration | Party | Tenure | Fiscal years attributed | Real GSDP open → close (₹ cr) | Real CAGR %/yr | Real per-capita CAGR %/yr | Tier | Basis & source |

Robust (consistent 2011-12-base official series): M. K. Stalin 9.05%/yr (2021-26, last year an estimate) > Jayalalithaa III-V/OPS 6.65%/yr (2011-17) > Palaniswami 4.67%/yr (2017-21, includes the COVID-19 year). Secondary criterion, real per-capita NSDP: 8.35% > 5.76% > 3.88%/yr.
Indicative (NSDP proxy or partial coverage): Karunanidhi 2006-11 ≈9.3%/yr (2004-05 base, 4 of 5 years); Jayalalithaa I 1991-96 and Karunanidhi 1996-2001 share the 7.74% 1990s decade average; Jayalalithaa II/OPS 2001-06 ≈5.9%; MGR 1977-87 ≈5.42%; Karunanidhi 1969-76 ≈3.63%; Kamaraj and Bhaktavatsalam ≈2.2% (1960s).
Unranked: Rajagopalachari, Annadurai, both Nedunchezhiyan acting spells, Janaki (24 days), Karunanidhi 1989-91 — no attributable fiscal-year observations.
DMK ≈7.0%/yr over 21 measurable government-years; AIADMK ≈6.0%/yr over ~30; INC ≈2.2%/yr over 13 proxy years (1960s only — its 1952-63 record is largely before any state series). President’s Rule spells (1976-77, 1988-89, 1991) are excluded. The gap partly reflects when each party governed: DMK’s measurable years cluster in high-growth national decades. State growth also tracks national cycles, monsoons, the 1991 reforms and COVID-19, so none of these numbers is a pure policy score.
Can: post-2021 shows the strongest two-year real-growth headline in the official estimates; growth has trended upward decade by decade since the 1960s under both Dravidian parties. Cannot: a single 1952-2026 league table — base years 1970-71, 1993-94, 2004-05 and 2011-12 cannot be divided into one another, early boundary years are unobserved, and short spells have no annual data. Rankings are therefore tiered, not a false-precision list.
Method: chronology reconciled from 2,904 extracted rows on Tamil Nadu chief ministers and President’s Rule (Assembly/reference lists); annual GSDP and per-capita NSDP from 136 statistical rows (StatisticsTimes compilations of MoSPI/CSO data, Tamil Nadu DES, PRS, RBI-derived reporting); historical real CAGRs from 150 period observations naming CSO, Planning Commission, RBI and academic sources; latest estimates from 30 rows on 2024-25/2025-26. Real = constant price (base stated per figure); nominal = current price; GSDP gross, NSDP net. Fiscal years attributed to the administration governing most of their months. Chaining, CAGRs and year-weighted party averages computed from these rows; duplicate and implausible extractions dropped. 2025-26 figures are estimates dated April 2026. Sector-level and district figures cut for space.
