Data Sampling & Measurement

Understanding the representativeness of different subpopulations is complex when developing nationally representative surveys, but it is even more challenging when building samples from publicly shared user posts. MDI researchers work to understand how to reweight samples to make them more representative of populations of interest. They also develop standards for constructing different types of variables and determining the reliability of different types of measurements. This is particularly important when developing measurements using big data sources, e.g. social media, newspapers, mobile phones, satellite images, etc. Representative samples and reliable measurements are necessary for developing evidence-based public policy. 

Place-based indicators project: This project seeks to advance easy access to high quality location-based indicators that use administrative data, federal statistical data, private data, open data, and everything in between.

S3MC: This project focuses on developing methods for using social media data to better understand public opinion as it relates to politics, the economy, and parenting. It also considers the role misinformation plays in public perceptions.

Mosaic: This project links survey and social media data to investigate ways to improve measurement of public opinion as it relates to vaccines, the economy, and K-12 education.
