There’s a rich amount of data on singlewomen and female-headed households in medieval Germany. Tax records for selected cities in the 14-15th centuries show between 17-25% of tax-paying households headed by women. Widows were often labeled as such in the records but it isn’t alway possible to clearly distinguish never-married women, though estimates suggest they may have been as many as half of these households. This continued in the 16th century with tax records indicating that 20-25% of tax-paying urban households were headed by women.
