This is a province-level study of the applicability of the Threshold Hypothesis. Development is expected to improve women's status at initial development stages. However, the relationship is anticipated to level off or change direction at later stages. A contextual measure of female status relative to men (measured as gender inequality in education, health, work status, occupation, and industry) is explained by three development measures (i.e., year, development level, and change in development level over two decades). Data from various census and surveys in the Philippines spanned three decades (1960s to 1980s). Results revealed that women were better off than men in health but women fell behind men on the other four domains. The Threshold Hypothesis was applicable for education and health. Although thresholds still apply, the reverse pattern was found for work status, occupation and industry. An unexpected second threshold was found at the extreme right of the development scale, which challenges the Modernization view on the status of women and development linkage for the education and health domains.
