Survival to extreme ages clusters within families. However, identifying genetic loci conferring longevity and low morbidity in such longevous families is challenging. There debate concerning the survival percentile that best isolates component longevity. Here, we use three-generational mortality data from two large datasets, UPDB (US) LINKS (Netherlands). We study 20,360 unselected containing index persons, their parents, siblings, spouses, children, comprising 314,819 individuals. Our...

It remains unknown how different types of sources affect the reconstruction life courses and families in large-scale databases increasingly common demographic research. Here, we compare family life-course reconstructions for 495 individuals simultaneously present two well-known Dutch data sets: LINKS, based on Zeeland province's full-population vital event registration (passive registration), Historical Sample Netherlands (HSN), a national sample birth certificates, with follow-up population...

The slavenregisters or slave registers of Suriname offer a unique perspective on the social and demographic history people in bondage. Thanks to citizen science project, archival sources were transcribed 2017 by hundreds volunteers. transcriptions used create longitudinal database more than 90,000 enslaved persons. This paper describes sources, data entry, cleaning standardized as well matching needed construct life courses. We discuss best practices we have learned along way. Finally, it...

A century after the Spanish Flu, COVID-19 pandemic has brought renewed attention to socioeconomic and occupational differences in mortality earlier pandemic. The magnitude of these pathways between occupation increased remain unclear, however. In this paper, we explore relation characteristics excess among men during Flu Netherlands. By creating a new coding for exposure disease at work, separate social status conditions viral transmission. We use data set based on men's death certificates...

Many historical and contemporary studies have shown that migrants enjoy survival advantages over non-migrants, even if they originate from higher mortality regimes a lower socio-economic educational status compared to non-migrants in the destination area. This so-called migrant advantage or healthy effect is explained various ways. One of main explanations refers selection effects area origin sense healthier individuals are more likely move less individuals. So far life-course analysis on...

In demographic research large-scale individual-level data have become increasingly available. At the same time, it remains unknown how varying sources affect reconstruction of individual life courses and families in databases. this paper, we conduct comparisons family course reconstructions 495 individuals simultaneously present two well-known Dutch datasets: LINKS-Zeeland HSN. The first dataset is based on a province’s full population vital event registration data; other national sample...

The limits to human lifespan are a widely discussed topic. Yet, later-life mortality and longevity generally studied from genetic perspective, while the social dimension has received less attention. This paper gives systematic overview of trends in for cohorts that were born late 18th 19th century, shows average population top survivors between 1800 1850 already growing older. These improvements survival similar both sexes among survivors, whereas gender equality life expectancy at age 50...

For the Netherlands, a rich new data source has become available which contains indexed civil certificates for multiple generations of individuals: LINKS. The current version dataset information on 1.7 million demographic events province Zeeland in 19th and early 20th centuries will be extended to other provinces Netherlands near future. To able study behaviour, life courses family relations need reconstructed from certificates. This paper describes steps that are taken move LINKS database,...

Studies have shown that long-lived individuals seem to pass their survival advantage on offspring. Offspring of parents had a lifelong over without parents, making them more likely become themselves. We test whether the enjoyed by offspring is explained environmental factors. 101,577 from 16,905 families in 1812–1886 Zeeland cohort were followed time. To prevent certain overrepresented our data, disjoint family trees selected. was included if age at death both known. Our analyses show...

A century ago, the 1918–19 influenza pandemic swept across globe, taking lives of over 50 million people. We use data from Dutch civil registry to show which regions in Netherlands were most affected by pandemic. do so for entire 1918 year as well first, second, and third wave that hit summer 1918, autumn winter 1919. Our analyses excess mortality was highest Oost-Brabant, Zuid-Limburg, Noord-Holland, Drenthe, Groningen, Overijssel, whereas low Zuid-Beveland, Utrechtse Heuvelrug, Achterhoek....

Vast amounts of heterogeneous knowledge are becoming publicly available in the form graphs, often linking multiple sources data that have never been together before, and thereby enabling scholars to answer many new research questions. It is not known beforehand, however, which questions might answers to, potentially leaving interesting novel insights remain undiscovered. To support during this scientific workflow, we introduce an anytime algorithm for bottom-up discovery generalized...

Reconstruction of historical persons and family ties is the bread butter many researchers genealogists. With increasing digital availability person records, scope depth reconstructions speaks to imagination Yet, lack standardisation in description data has hurt interoperability sustainability both small large databases. Persons Context, or PiCo, presents a model for records within Resource Description Framework (RDF). RDF Linked Data specifically designed clear, unambiguous information...

Are daughters of older mothers less fertile? The human mutation rate is high and increases with chronological age. As female oocytes age, they become functional, reducing chances at successful reproduction. Increased oocyte loads advanced age may be passed on to offspring, decreasing fertility among born mothers. In this paper we study the effects maternal ageing her daughter's fertility, including total number children, last birth, neonatal mortality children. We histories two generations...

LINKS stands for 'LINKing System historical family reconstruction' and is a software system to link nominal data from the Dutch archives ultimately reconstruct individuals families. We present background philosophy of this matching explain its structure functioning. Currently core consists indexed civil certificates. These certificates are available 1812 — start Vital Registration until year they confidential based on privacy laws. For more than 20 years, thousands volunteers have been...
