Quarterly GDP for Ireland since 1950

Abstract: We construct estimates of quarterly GDP (and GNP) for Ireland from 1950, linking to official data from 1995 onward, using a novel factor-augmented Chow-Lin interpolation. Compared to the only alternative series (OECD, 2025), our estimates exploit the variation in a large number of official quarterly economic data and are broadly consistent with contemporary reports. Our series permits a more granular identification of turning points in the Irish economy than was previously possible. The frequency and magnitude of quarterly contractions in the 1950s and 1980s dwarfed those of other decades resulting in lower average growth rates. In contrast, the 1990s are confirmed as a decisive period of higher growth and rapid convergence.
