The British census intended to capture regular employement, so whilst more men and women might have worked, it was casual and therefore not included.Historians argue that the census doesn’t give us an accurate picture though. contemporary household budgets reveal that more women did in fact work than what was officially revealed.
also, the whole voluntary point I made was merely a theory. I was linking the rise of male trade unionism ect but it turns out I was wrong. Oh well.
YeAh, that we already discussed when I mentioned the household budget source. Household budget along with actual first hand Victorian reports is what historians used to get an insight of women’s work.
For example being a son/daughter/wife of a farmer was regarded as an occupation in 1851 however in 1881, they were regarded as unemployed unless they worked full time on the farm themselves.
As for the pre census data:
“In the pre-census era, the data available on the participation of women in different occupations can be characterized as partial, sporadic and error-laden. As a result, historians using different data sources often propose dissimilar occupational structures for women. For example, church court records indicate that making clothes and laundry were the most important female occupations the eighteenth century (Earle 1989) whereas criminal court records suggest shop keeping and the selling of food & drink dominated women’s work (Erickson 2008).”
Your source of 66 % married women working used 1161 households which i don’t think is a large enough sample size to represent the entire UK population which was recorded at 26 million in 1881 unlike the british census which recorded every single person in the UK. The sample size was collected from contemporary social commentators, parliamentary papers, local archives,provincial record offices,and working class autobiographies. There are small irregular geographical pockets in the UK where married women work >35 % but the average is less than <5 %. A wife who helped their husband once a week on the farm for an hour would also be considered employed.
