The Big Cities Health Coalition (BCHC) provided two "mini-grants" to graduate students for work related to the Big Cities Health Inventory (BCHI) Data Platform. The data platform is an innovative tool that allows the user to easily explore, compare and share 30,000 public health data points from 30 cities. These students were asked to analyze data from the platform and present their findings at the National Association of County and City Health Officials (NACCHO) Annual Conference in 2018.
