Hypothesis
This study aims to estimate the number of partnerships that individuals make, their stability, and the degree to which mixing is assortative with respect to age.
Conclusion
The study found that intimate contacts are stable over short time periods, while casual contacts do not repeat with the same individuals.
Supporting Evidence
- Intimate contacts are stable over short time periods.
- Casual contacts do not repeat with the same individuals.
- Contacts were increasingly assortative as intimacy increased.
- The study provides insights into the dynamics of contact networks.
Takeaway
The study looked at how often university students meet different people and found that close friends are more likely to be of similar ages.
Methodology
Undergraduate students recorded details of their contacts over three days, focusing on the intimacy level of each contact.
Potential Biases
Self-reported data may lead to under-recording of contacts, especially at lower intensity levels.
Limitations
The study's convenience sample limits the generalizability of the results to the population at large.
Participant Demographics
Participants were 29 university students aged 18 to 24, with a mean age of 20.5 years.
