In the age of big data, more extensive information by place, person and time are becoming available to measure public health impact and implementation needs. “Big data” refers to large amount of information, such as data from biobanks (e.g. Big Data encompasses the ever increasing amounts of health-related information from disparate sources that can provide more precision by place, time, and persons than previously available. Required fields are marked *. Our ability to improve population health depends to a large extent on collecting and analyzing the best available population level data on burden and causes of disease distribution, as well as level of uptake of evidence-based interventions that can improve health for all. Quantitative data uses numbers to determine the what, who, when, and where of health-related events (Wang, 2013). In principle, big data could point to implementation gaps and disparities and accelerate the evaluation of implementation strategies to reach population groups in most need for interventions. The seminar was well attended, with more than 200 participants. The Summit brought together representatives of schools of public health across the country to shape the future of public health applications of data science.
