What is an ecological study?
An ecological study is a study where the level of data analysis is at a group level, rather than an individual level. So instead of individuals ranked by exposure, it is groups that are used instead.
An disease detective who happens to experiment with meteorology when she is sick of testing her scrambler.

That's right. Specifically, numbers such as mean and incidence rates are used to assess the group(s) of interest.

Why did rates of disease transmission increase so rapidly in the first part of the 20th century?
World War I, and to a lesser extent, World War II, brought soldiers all over the world and then back home. The Spanish Flu pandemic is the most severe result of these transmissions.
