More importantly, what data do you have and what form is it in? Is it point data in featureclass, shapefile or tabular format?
Is it point or polyline or even polygon geometry? Is it for different time periods?
The data is in tabular format for one period time.
Best Regards,
perhaps you could share a few rows so we can see if there are any spatial coordinates or designators, or from and to information. Migration implies movement from one location to another, so this information and its form would be useful.
I would stick with a table and explain it... skip the map, it won't add anything.
