What is cross-sectional data in economics?

Cross-sectional data refer to observations of many different individuals (subjects, objects) at a given time, each observation belonging to a different individual.

What is cross-sectional ratio?

Why do we use cross-sectional data?

Because you only collect data at a single point in time, cross-sectional studies are relatively cheap and less time-consuming than other types of research. Cross-sectional studies allow you to collect data from a large pool of subjects and compare differences between groups.

What is the difference between cross-sectional and panel data?

Cross sectional data means that we have data from many units, at one point in time. Time series data means that we have data from one unit, over many points in time. Panel data (or time series cross section) means that we have data from many units, over many points in time.

How do you collect cross-sectional data?

When would you use a cross-sectional study?

Cross-sectional designs are used for population-based surveys and to assess the prevalence of diseases in clinic-based samples. These studies can usually be conducted relatively faster and are inexpensive. They may be conducted either before planning a cohort study or a baseline in a cohort study.
