Parallel Progress Without Catch-Up: Human Development Convergence Across Central Java

Abstract

Provincial planning documents in Indonesia routinely adopt the Human Development Index as a headline target, yet an aggregate target can be met while the gap between constituent districts remains untouched. This study asked whether human development disparity across the thirty-five districts and cities of Central Java narrowed between 2019 and 2023. Index and poverty figures for all thirty-five jurisdictions were compiled from official statistics reproduced in the Governor's accountability reports. Three complementary instruments were applied: a Klassen typology modified to use index level and index growth, sigma convergence measured by the coefficient of variation, and absolute beta convergence estimated by regressing average growth on the logarithm of the initial index. The provincial index rose by 1.66 points, and every jurisdiction improved, but the absolute range held at 17.04 points and the coefficient of variation fell only from 6.083 to 5.956 per cent. The beta coefficient was negative yet insignificant at the five per cent level, implying a convergence speed of 0.55 per cent per year. Twelve jurisdictions were advanced and fast-growing, seven advanced but slowing, thirteen developing rapidly, and three lagging on both dimensions. Contrary to the prevailing policy narrative, the genuinely stalled jurisdictions were located in the central highlands rather than along the western north coast. The study argues that dispersion indicators belong alongside attainment targets in regional planning documents, and that lagging regions require differentiated rather than uniform treatment.
