I`m not a developer and looking for ways that would allow to get the total count of items within a specific column in SharePoint 2013 List.
I would create a new view, filtered by your column equals your particular value. In the Totals section of the view configuration screen, tell it to count on any of the listed fields. Save the view. When you visit the view, it will be filtered and there will be a total at the top of the view that tells you how many items there are.
