The Missouri Information for Community Assessment (MICA) system was developed to make health data accessible at the local level through an easy to use format. This is an interactive system that allows users to summarize data, calculate rates, and prepare information in a tabular format for presentation.

MICA provides data on health conditions, including causes of death, births, hospitalizations, emergency room visits, etc. Users can choose from among the many conditions, generate data tables by year of occurrence, age, gender, race, and county and zip code of residence, and obtain age-adjusted rates. MICA also allows users to download tables into other applications in order to produce charts or graphs.

Data for MICA are extracted from files maintained by the Missouri Department of Health and Senior Services and summarized for the highest level of detail from files maintained by the Missouri Department of Health and Senior Services. Frequencies are pre-computed for each combination of the variables. This provides two major advantages: the response time to create and return a table is usually less than five seconds and no individual record can be accessed. Confidentiality rules have been developed to protect the privacy of individuals.

The MICA system uses an HTML web page in the browser which sends information to a hypertext server. This server has a PHP module which processes this information, reads data from a mysql database and sends a table back to the browser.
