macrodatasets

Macrodatasets are collections of data that are aggregated to a level where individual units are not identifiable. This aggregation can occur across various dimensions, such as geographical areas, time periods, or population groups. For example, a macrodataset might contain the total number of households in a city, the average income per region, or the unemployment rate for a specific country over several years. The primary characteristic of macrodata is the absence of microdata, which would represent individual entities like single households, persons, or firms.

The creation of macrodatasets often involves the summarization or aggregation of microdata. This process can be done by statistical agencies, research institutions, or even by combining publicly available information. The purpose of macrodatasets is to provide a broad overview of phenomena, enabling the analysis of trends, patterns, and relationships at a larger scale. They are crucial for macroeconomic analysis, policy formulation, and understanding societal-level changes.

While macrodatasets offer a valuable perspective, they also have limitations. Due to the aggregation, it becomes impossible to study variations within the aggregated units. For instance, knowing the average income of a city does not reveal the income distribution among its residents, nor does it highlight the circumstances of specific low-income households. Therefore, the interpretation of macrodatasets requires an awareness of the underlying aggregation process and the potential loss of detail.
