Helsinki Institute for Demography and Population Health presents PopHel Talks, where we showcase our latest research. Our work explores various topics in demography and population health, with an emphasis on social inequalities. If you are interested in hearing our presentations, please register here so we can send a Zoom link to you.

Aapo Hiilamo (Max Planck Institute for Demographic Research and MaxHel Center) presents: Children’s out-of-home care in Finland, 1993–2020: lifetime risks, expectancies, exit routes, and number of placements for synthetic cohorts. This presentation seeks answers to questions like:

• How likely it is that a newborn child will ever enter out-of-home care?
• How many years, on average, this child will spend in care?
• How likely it is that the child will ever reunify with their family after being placed in care?

We warmly welcome you to join us for our seminar PopHel Talks in Zoom. Our first presenter will be Alvaro Obeso with the title “Microevolutionary genetic processes of Roma population based in the Basque country: A Short Tandem Repeat based study.” This presentation will focus on: 

• Understanding the microevolutionary processes experienced by the Roma population during their migration from northwestern India, including the impact of genetic drift and gene flow. 
• Characterizing the Y chromosome lineages to gain deeper insight into the male ancestry, with evidence suggesting a possible southeastern Indian origin.
