In “Bayesian Projection of Extant Refugee & Asylum Seeker Populations,” @herbps10.bsky.social & @adrianraftery.bsky.social propose a time-series model for projecting refugee & asylum seeker population statistics by country of origin. @nyumedpostdocs.bsky.social read.dukeupress.edu/demography/a...

Our paper with Ginevra Floridi out in Sociological Science now!

We use sequence analysis, LCA & survival models to map how parental financial and co-residential support unfolds across young adulthood. We find 3 distinct pathways & a gendered relationship between marriage and independence.

New working paper up on SocArxiv! osf.io/preprints/so.... I use the 1940 Census and linked mortality records in combination with an IV-design to study the causal effects of racial segregation on longevity. I show that segregation reduces both Black and White longevity.

This method would benefit from more application, validation, and refinement in real humanitarian settings ...

Special thanks to fantastic collaborators from NGO @impact-initiatives.bsky.social for supporting methods development in this space!

This design could be deployed remotely in settings where operational constraints prevent humanitarian groups from reaching insecure areas, meaning it could potentially be applied to estimate death rates in a wide range of humanitarian emergencies.
November 19, 2025 at 5:16 AM
This new method can be used to monitor trends in crude death rates over time.
November 19, 2025 at 5:16 AM
However, the household estimate from the *probability* sample was much higher than other estimates, which may reflect strategic over-reporting (high levels of NGO operations in the area have been hypothesized to create incentives to overreport deaths).
November 19, 2025 at 5:16 AM
From the quota sample, our estimates based on different types of respondent reports (i.e., reports on neighbors, kin, and household) produce similar and plausible crude death rate estimates.

As we reweighted to account for selection into the quota sample, the estimated death rates increased.
November 19, 2025 at 5:16 AM
To account for selection into our quota sample, we constructed survey weights under several scenarios reflecting different hypothetical levels of auxiliary data availability for weighting targets.
November 19, 2025 at 5:16 AM
An advantage of the network approach is that each interview provides mortality information on many more people than a typical mortality survey that asks respondents only about their household or siblings.
November 19, 2025 at 5:16 AM
Qualitative fieldwork suggested testing two different types of personal networks as the basis for estimates: deaths among immediate neighbors and deaths among kin.
November 19, 2025 at 5:16 AM
We did several weeks of in-person fieldwork (cognitive interviews, focus groups, etc.) to better understand the types of social networks people could report accurately on in this setting.

— Quota sample: sampled respondents from 3 health zones at major transit hubs (e.g., markets, taxi stops, ports, health clinics, and footpaths) who were coming into Kalemie City (N = 2,526)

— Probability sample: sampled respondents probabilistically across 3 health zones in their HH (N = 2,785)

We collected original data in Tanganyika Province, Democratic Republic of the Congo, a realistic setting where such emergencies have happened in the past.

Study design involved two data collection efforts: a quota sample possible in a humanitarian emergency and probability comparator sample.
November 19, 2025 at 5:16 AM
We adapt the network survival method to the unique setting of humanitarian emergencies.

The idea behind the network survival method is that respondents can report on 1) the size of their social network and 2) deaths in their social networks. This info can be aggregated to estimate death rates.
November 19, 2025 at 5:16 AM
Reliable estimates of death rates in complex humanitarian emergencies are critical for assessing the severity of a crisis and for allocating resources. However, in many humanitarian settings, logistical and security concerns make conventional methods for estimating death rates infeasible.
November 19, 2025 at 5:16 AM
Our new paper develops and tests a network-based method for estimating death rates in complex humanitarian emergencies.

Women are 19% less likely to use the internet and 8% less likely to own a mobile phone than men.

That’s 320 million fewer women online and 190 million fewer with phones globally 🌍
