I built the website with Quarto, R, GitHub, and host it through Netlify. Curious how it’s made? The source code is available on my GitHub repository: github.com/bhofstra/aca.... I licensed it through CC-BY 4.0, so feel free to re-use what you need.

I’m excited to share the launch of my new website: bashofstra.com!

This site brings together all my work in a clear, accessible format. The new website is clean, minimal, responsive, and scalable and works seamlessly on desktop and mobile.

Recently presented at the CREST Sociology seminar, now published in @ssreditorial.bsky.social: @mtorre.bsky.social's "The uneven effects of gender parity"

Aflevering 200 Journalistiek programma met een eigen kijk op het dagelijks nieuws.

📺 RTL EditieNL besteedde aandacht aan en interviewde mij over ons onderzoek naar de kennissenkring van Nederlanders. Samen met Beate Völker, Rense Corten, en Frank van Tubergen onderzochten we hoe groot deze netwerken zijn en hoe homogeen ze blijken te zijn.

Vanaf 7:32: www.rtl.nl/nieuws/uitze...

De @volkskrant.nl schreef een stuk over ons onderzoek naar sociale contacten en haar scheidslijnen! Zie hieronder:

Onderzoek met Beate Volker, @rensec.bsky.social, en Frank van Tubergen.

Een Nederlander kent zo’n 568 mensen: ‘Soort zoekt soort en opleiding is een bepalende factor’

Nothing like having your Social Networks article (as seen at #Sunbelt2024) published while attending #Sunbelt2025!

You can find the paper here: www.sciencedirect.com/science/arti...

You can find the replication website to the paper here: bhofstra.github.io/netsize_dutch/

(PS: fitting that this gets out while I'm currently at the Sunbelt conference of the International Network of Social Network Analysis!)

Additionally, we find a pretty strong presence for gender and educational homogeneity.

These findings have important implications for Dutch social structure as to who is at risk to become socially isolated and as to where social barriers between groups exist.

We find fascinating patterns where average network size across a representative set respondents in the Netherlands is about 518 people. But more importantly, it decreases with age, unemployment, lower income, lower house values, lower education, and fewer people in a household.

This is a project that came out of our earlier popular publication at Quest where they asked us similar questions!

In this paper we use computational methods (for insiders, specifically the Network Scale-Up Method) to calculate both network size and its determinants, as well as network homogeneity and its determinants.

Thrilled to share my latest publication in the journal Social Networks, together with Beate Völker (lead), @rensec.bsky.social, and Frank van Tubergen.

After a pretty gruesome train ride, finally arrived in Paris for #sunbelt #sunbelt2025. Can’t wait to hear about all the amazing network studies. Shoot me a message if you want to meet or catch up!

As some of you guessed, the two models are statistically indistinguishable. The answer is Model 1, but there was no way to tell from the data. I was very surprised when I first saw this. Here we show that this confounding of heterogeneity and reinforcement is general: www.pnas.org/doi/10.1073/...

What about research sitting at the intersection of the union of two literatures…?

Two peas in a pod? How to mix methods in ethnic and migration studies This introduction to the Special Issue on ‘Two peas in a pod? How to mix methods in ethnic and migration studies’ highlights scholars’ experiences and reflections on doing mixed methods research wi...

Mixed methods milestone! 🛠️Check out this Special Issue edited by @nielsspierings.bsky.social, Tine Davids & I! No textbook perfections but practical realities on how to mix methods in migration studies and which structural barries keep mixed methods from thriving! www.tandfonline.com/doi/full/10....

Where my paper is on the quantitative end of mixing methods, the special issue includes other important pieces on mixing methods with all sorts of (quantitative and qualitative) data types.

A thank you to the special issue editors @nellageurts.bsky.social, Tine Davids, and Niels Spierings for their thoughtful feedback, and for creating a space for important work on mixing methods.

And a cautionary tale on rushing into data linkages without seriously considering the implications for things like representativity and selection bias. I include concrete examples and steps on how to address these issues.

This paper is both an invitation and a cautionary tale: an invitation to think more deeply about the possibilities of sociological research that merges traditional survey data with digital traces.

Through a use-case on ethnic background and social relationships, I highlight (through experiences in several prior papers) some of the conceptual and practical challenges that come with trying to bridge these data worlds.

In this piece, I take a critical look the (sometimes) celebrated idea of linking survey data with digital footprints. I explore not just the why—but the why not, and perhaps more importantly, the how not.

The why (not) and how (not) of survey to digital footprint linkages: a use-case of ethnic background and social relationships In the last decade, there has been a rise of mixed-method-big data approaches in the social sciences. One such approach is linking survey data with digital footprint data. Yet, some of the fundamen...

Thrilled to share my new open access paper: "The why (not) and how (not) of survey to digital footprint linkages: a use-case of ethnic background and social relationships" in Journal of Ethnic and Migration Studies.

Wauv!! My beyond awesome colleague in the Copenhagen sociology department, @mathiaswullum.bsky.social, has just published in @nature.com!!

A very cool piece that argues for the many benefits of applying intersectional perspectives in science!

That is truly appalling, am so sorry to hear that.

Stop de cynische sloop van onderzoek en onderwijs. Fundamenteel en toegepast onderzoek die onze toekomst vormgeven gaan verloren. Onderwijs verschraalt, studenten zijn de dupe. We raken decennialange opgebouwde kennis in vakgroepen, onderzoekers, docenten, en opleidingen kwijt. Doe het niet!
