According to LDS there was a "Police Census" taken in DC in 1894 and 1897.
LDS also referenced the "Annual Report of the Commissioner of the District of Columbia"

Has anyone researched these "DC Census's"? Where did you find them? Have they been abstracted?

Is anyone familiar with the "Annual Report...."? Was the entire census listed in the report or perhaps a summary?

Thanks in advance for any assistance that you can provide.
