Under Topics, you can view a list of keywords that are associated with datasets in the open data portal. The NCSI selected the list of topics to cover in the portal and approves all tags used in public datasets in the portal. In the image below, you can see keywords such as Business, Demography, Economy, and Health. Clicking on a keyword displays the dataset(s) available on the topic in the portal. 


NOTE: Registered users may see different lists of Topics when they log into the portal based on tags they have assigned to private datasets or other users have assigned to datasets and shared directly to other users.
