Recent studies of male occupations have used Anglican baptisms as a source. However, in areas where nonconformity was strong, a significant proportion of baptisms were missing from parish registers: in Wales, around a quarter of births were to Nonconformist fathers in the years 1813–1820. This study analyses whether there were significant differences between the occupations of Anglican and nonconformist fathers based on a 14 per cent sample of Welsh baptisms. Revised estimates suggest that Anglican data underestimate employment in mining and industry. These estimates are used to give an overview of the Welsh economy c.1817.

教区记录中缺失：英国国教和不墨守成规的职业差异以及威尔士 c.1817 的经济

最近对男性职业的研究以英国国教的洗礼为来源。然而，在不循规蹈矩的地区，教区登记册中遗漏了相当大比例的洗礼：在威尔士，1813-1820 年间，约有四分之一的父亲是不循规蹈矩的父亲。这项研究基于 14% 的威尔士洗礼样本，分析了英国圣公会和不循规蹈矩的父亲的职业之间是否存在显着差异。修正后的估计表明，英国国教的数据低估了采矿和工业的就业。这些估计用于概述威尔士经济c .1817。
