Hypothesis
What are the national twinning rates across developing countries?
Conclusion
The study provides a comprehensive overview of twinning rates, revealing significant regional variations across developing countries.
Supporting Evidence
- The average national twinning rate across the 76 countries studied was 13.1 per 1000 births.
- Very low twinning rates were found in East and South-East Asia, while high rates were observed in Central Africa.
- Data was collected from a large sample of over 2.4 million births.
Takeaway
This study looked at how many twins are born in different countries and found that some places have a lot of twins while others have very few.
Methodology
Data was collected from 150 Demographic and Health Surveys in 75 low and middle income countries, focusing on births from the last ten years.
Potential Biases
The data may be biased due to the exclusion of stillbirths and reliance on survey data.
Limitations
The study may not account for stillbirths, which could lead to underreported twinning rates.
Participant Demographics
Women aged 15-49 from low and middle income countries.
