Is The Census Constitutional?

Article 1, Section 2 of the Constitution defines the legitimate need of the enumeration(census). That need covers the apportionment of congressional representatives; nothing else is mentioned. Here is the page from the Census Bureau website telling us what the information is used for. I also included the commercial that been airing during NCAA basketball games which pretty well covers it - they need the census for central planning and wealth redistribution.
