Why do we choose one language over another? Rival views see language frontiers as exogenous, driven by policy, or endogenous, determined by social, cultural and economic forces. We study language loss in nineteenth-century Ireland's bilingual society using individual-level data from the 1901...

Geary and Stark find that Ireland´s Post-Famine per capita GDP converged with British levels, and that this convergence was due to TFP growth rather than mass emigration. We devise new long-run measurements of human capital accumulation in Ireland in order to facilitate an assessment of sources...

What impact do famines have on survivors? We use individual-level data on a population exposed to severe famine conditions during infancy to document two opposing effects. The first: exposure to insufficient food and a worsened disease environment is associated with poor health into adulthood -...

Using the Irish experience of the Spanish flu, we demonstrate that pandemic mortality statistics are sensitive to the demographic composition of a country. We build a new demographic database for Ireland's 32 counties with vital statistics on births, ageing, migration and deaths. We then show...

This is a dataset of vital statistics and cohort component population estimates at a spatially-disaggregated level for the island of Ireland for the period 1911-1920. The raw data were digitised by the authors using official UK government statistics. The population estimates were then derived by...

The frequency at which age data heap at round ages can be used to infer people’s ability to count. Földvári, Van Leeuwen and Van Leeuwen-Li (FVV) contend that gender specific trends in numeracy derived from age heaping in census data are unreliable because women’s ages are adapted to those...

The quality of age reporting in Ireland worsened in the years after the Great Irish Famine (1845-1852), even as other measures of educational attainment improved. We show how demography partly accounts for this seemingly conflicting pattern. Specifically, we argue that a greater propensity to...
