Table with name, address and district.  District can be multiple values per person. Can look like this:

John Doe  123 Main St   District 1
                                           District 2
                                           District 3
Jane Doe   352 Flower Ave  District 1
Jude Doe   456 Sunset Rd   District 1
                                                 District 4
 
Everybody has District 1.  Some ONLY live in District 1 with no additional districts.
I only want the people who live in District 1 ONLY.  Not the ones who live in District 1 plus other districts.
Problem is, if I do a select where district is "not in a list of" and exclude all the other districts, I still get them because...yeah they live in District 3 which is not District 1.  So it returns those.  How do I get just the people who live in District 1 ONLY?
 
Thanks in advance.

The District field contains text, like "District 1" so the count formula is throwing an error on me.

so if you insert a summary of the District as a COUNT at the group level of person
you should get this
John Doe  123 Main St   District 1
                                           District 2
                                           District 3
Count=3
Jane Doe   352 Flower Ave  District 1
Count=1
Jude Doe   456 Sunset Rd   District 1
                                                 District 4
count=2
now you can use that data to select at a group level
COUNT(table.district,table.name)=1
