...Nowadays, it is common in Historical Demography the use of individual-level data as a consequence of a predominant life-course approach for the understanding of the demographic behaviour, family transition, mobility, etc. Advanced record linkage is key since it allows increasing the data complexity and its volume to be analyzed. However, current methods are constrained to link data from the same kind of sources. Knowledge graph are flexible semantic representations, which allow to encode data variability and semantic relations in a structured manner.
In this paper we propose the use of knowledge graph methods to tackle record linkage tasks. The proposed method, named WERL, takes advantage of the main knowledge graph properties and learns embedding vectors to encode census information. These embeddings are properly weighted to maximize the record linkage performance. We have evaluated this method on benchmark data sets and we have compared it to related methods with stimulating and satisfactory results.
Never before the nineteenth century had Europeans, especially in the south, adopted cordons sanitaires in such great numbers or at such a fast rate. This article aims to analyse the process of the ...rationalisation and militarisation of the cordons sanitaires imposed in the fight against epidemics during the nineteenth century on the Mediterranean island of Majorca (Spain). These cordons should be understood as a declaration of war by the authorities on emerging epidemics. Epidemics could generate sudden and intolerably high rises in mortality that the new liberal citizenship found unacceptable. Toleration of this type of measure was the result of a general consensus, with hardly any opposition, which not only obtained the support of scientists (especially in the field of medicine) but also of most of the local and provincial political elite, and even of the population at large.
Abstract
A rich tradition exists on measuring human capital in historical societies through basic mathematical skills using the method of age heaping. In this article, we novelty propose to calculate ...it also through the analysis of the consistency in individual consecutive age declaration statements in five towns of Baix Llobregat’s county (Barcelona, Spain) during the nineteenth and early twentieth centuries. The region underwent a proto-industrialization in the eighteenth century and was one of the main wool and cotton textile producers in the nineteenth century in Catalonia. Our main results show that (I) numeracy levels in this county were above the Spanish average in the whole period and, during the first years of the nineteenth century, ahead of countries such as Italy, Portugal and the USA. However, its numeracy dropped from 1880’s due the early industrialization of Catalonia in the Spanish and Southern Europe context, the existence of child labor in the factories and that also coincided with the phylloxera crisis. (II) To this effect, women presented lower levels of numeracy than men, but their levels tended to converge. (III) As regards emigrants, those who came to the rest of Spain had the lowest level of numeracy compared to the natives. (IV) Moreover, we found that literacy, the 1901 education reform and a higher socioeconomic status had a positive effect on reporting ages consistently over time. (V) Finally, we prove a positive association between systematically reporting ages ending in 0 or 5 and having a higher individual error in age statements along the life course.
The Barcelona Historical Marriage Database (BHMD) gathers records of the more than 600,000 marriages celebrated in the Diocese of Barcelona and their taxation registered in Barcelona Cathedral's ...so-called Marriage Licenses Books for the long period 1451–1905 and the BALL Demographic Database brings together the individual information recorded in the population registers, censuses and fiscal censuses of the main municipalities of the county of Baix Llobregat (Barcelona). In this ongoing collection 263,786 individual observations have been assembled, dating from the period between 1828 and 1965 by December 2020. The two databases started as part of different interdisciplinary research projects at the crossroads of Historical Demography and Computer Vision. Their construction uses artificial intelligence and computer vision methods as Handwriting Recognition to reduce the time of execution. However, its current state still requires some human intervention which explains the implemented crowdsourcing and game sourcing experiences. Moreover, knowledge graph techniques have allowed the application of advanced record linkage to link the same individuals and families across time and space. Moreover, we will discuss the main research lines using both databases developed so far in historical demography.
Labour market transformation and inequality were fundamental aspects in the transition to the industrialisation. This article reconstructs the Barcelona’s area economic structure across the 18th and ...19th centuries through the Marriage Licences of the Barcelona’s Cathedral. These documents registered a proportional tax paid by the spouses’ according to their occupational and social status. Since 1780, an important decrease in the primary sector and an increase in the secondary and tertiary sectors are observed. Inequality between economic sectors rose and also within the secondary sector (textile) due to the proletarianization of the workers. Conversely, there was not an increase in inequality in the primary sector while it decreased in the tertiary sector.
Este estudio quiere contribuir al análisis regional del papel de los criados rurales en el surgimiento de los mercados de trabajo agrarios en la isla de Mallorca en el siglo XVII. El objetivo del ...artículo es caracterizar los criados rurales del sector olivarero en la isla de Mallorca para mediados del siglo XVII. Las principales fuentes serán los libros de cuentas de los predios del segundo Conde de Formiguera, Ramon Burgués-Saforteza, pues no se disponen de otras fuentes generales o locales de carácter socio-ocupacional. A partir de la sistematización de esa información el estudio sugiere que los mozos en los predios analizados eran trabajadores adultos y mayoritariamente eran contratados por breves períodos de tiempo, lo cual demostraría que tenían unos perfiles sociales y demográficos distintos al de los criados de las regiones europeas del norte donde dominaban los criados rurales jóvenes y solteros con contratos de larga duración.
This article aims at studying the intergenerational transmission of status within farmers and artisans in the preindustrial area of Barcelona from a siblings' attainment perspective in a context of ...impartible inheritance. The data source used are the Marriage License Books from the Barcelona's Diocese compiled in the Barcelona Historical Marriage Database, which for the sixteenth and seventeenth centuries provides a rich and continuous demographic and socioeconomic information through the use of the multilevel regression analysis. Our main findings points out the important family impact on the social fate of children. First-married children were the maximal inheritors of parental statuses in all social groups, especially for farmers and artisans, the former being more linked to ascription than the latter. However, farmers were found to be the group with the highest intergenerational occupational inheritance although artisans were who transmitted at most their social group. This divergent effect is due to the different strategies, or in a way a same strategy, used on non-first-married children to whom, families from the two social groups, when not able to transmit the same parental occupation, preferred to position the offspring in artisans' careers thanks to a favourable context of a flourishing manufacturing industry at the countryside.

It has been amply demonstrated that individuals' reproductive capability is the key explanatory phenomenon for understanding onomastic disappearance during the early modern period. This article ...analyzes the evolution and consequences of surname extinction in a specific population: Catalonia in the sixteenth and seventeenth centuries. In this article two aspects are examined. First, the observed disappearance of surnames is estimated through historical data collected in the Llibres d'Esposalles (Marriage Books) from 1481 to 1600 at Barcelona Cathedral. Second, the estimated natural extinction of those surnames registered in 1481 is forecast by applying a statistical branching process.
