What is Cross- Sectional
Cross-sectional studies (also known as Cross-sectionalanalysis) form a class of research methods that involve observation of some subset of a population of items all at the same time, in which, groups can be compared at different ages with respect of independent variables. Cross-sectional data in statistics and econometrics is a type of one-dimensional data set. Cross-sectional data refers to data collected by observing many subjects (such as individuals, firms or countries/regions) at the same point of time, or without regard to differences in time. Analysis of cross-sectional data usually consists of comparing the differences among the subjects. A Cross-sectional regression is a type of regression model in which the explained and explanatory variables are associated with one period or point in time. This is in contrast to a time-series regression or longitudinal regression in which the variables are considered to be associated with a sequence of points in time.
advantage of cross sectional study?
Yes, We can design a cross sectional study which its data collected in a retrospective format, so this study is called cross sectional retrospective study.

Cross sequential studies combine both longitudinal and cross sectional methods in an attempt to both shorten the length of the research and minimize developmental assumptions
Cross-sectional studies are also known as transversal and prevalence study. It is a form class of research methods that is all about population and the different case control studies that provide data on all the population that is under study.
A cross-sectional study is a type of observational research that analyzes data collected from a population at a single point in time to assess relationships between variables. In contrast, a retrospective study looks at past data to investigate possible links between exposure and outcome variables.
A cross-sequential research study is a combination of cross-sectional and longitudinal research methods. It involves studying different age groups at multiple points in time to examine both age-related and time-related changes over the course of the study. This approach allows researchers to better understand how development unfolds over time and across different age cohorts.
The quickest way to study changes over the life span is through cross-sectional research.

cross sectional
Basically it is not. However, there are studies being tiltled as prospective cross sectional study, but these kind fo terms should be used with caution and clear explanation.
