The findings highlight the importance of understanding social mobility's impact on fertility, emphasizing the value of DRMs in historical research. Looking forward to further exploration in this area! 🔍

Our study uses Swedish data from 1905 to 2015, revealing a constant but small negative association between upward social mobility and fertility. This was especially noticeable in the oldest cohorts. 📊

8/8 Is the rise of social mobility tied to a decline in family influence? Our findings suggest otherwise. Kinship, particularly sibling ties, continued shaping social outcomes even during industrialization.

7/8 First-married sisters often played important roles in supporting siblings, even within rigid inheritance systems like Catalonia's single-heir system? Marrying "down" wasn’t always a disadvantage—it could also be strategic.

6/8 The influence wasn’t limited to brothers. First-married sisters also shaped their siblings' mobility, challenging ideas like women’s hypergamy.

5/8 First-married brothers (FM siblings) significantly influenced the SES of their siblings. This wasn’t about replacing parental roles but about new intragenerational cooperation.

4/8 Proto-industrialization! As societies transitioned, horizontal ties (siblings) increasingly supplemented or replaced vertical ties (parents). A sign of family cooperation, not loss of family influence.

3/8 Traditionally, parents were seen as the main influence on children’s socio-economic status. But from the 18th century, siblings—especially first-married brothers—began playing a larger role. What can explain this shift?👇

2/8 Research Insights: Social mobility didn’t erase family influence; it restructured it. Horizontal ties gained prominence, aligning with proto-industrial dynamics.

1/8 Our latest research deals with family influence on socio-economic outcomes in the Barcelona area (16th–19th centuries) using the Barcelona Historical Marriage Database (BHMD). We use unique data combining both occupational and economic information!

The historical #fertility transition began with stopping, and then involved both stopping and spacing, with similar patterns across #social classes. Evidence from applying cure models to #microdata from Southern Sweden. New publication 👉https://www.demographic-research.org/articles/volume/51/40
