The following is a list of MSAs over 1 million, their corresponding UAs and the percentage of the MSA that is represented by the UA. These are listed in descending order from the highest percentage to the lowest percentage. A few of the MSAs have urban areas that exceed their MSAs because the UA actually consolidates or spills over into an adjacent MSA. For those instances, I have combined the population of the two MSAs (not the CSA) and compared that number with the UA. This is the case for San Francisco & San Jose per the data set. For Los Angeles, I am presuming that that its UA is spilling into the Riverside MSA since Riverside doesn't have an UA listed in the source and the Inland Empire is millions of people in size. For Las Vegas, I can't identify or presume a likely cause of the UA being larger than the MSA; it's just listed as having a UA larger than its MSA.
A caveat is that the MSAs are based on July, 2015 numbers while the UAs are based on a 2016 report. Sources linked below.
Format for the list is MSA by listed first city followed by MSA population followed by UA population followed by UA percentage of MSA.

If I left any metros off other than the ones that I combined due to how the UA's are reported, please point out the omissions.
