Tex Texin posted on my indication that only U+00A0 NO-BREAK SPACE and 
U+202F NARROW NO-BREAK SPACE are available in Unicode for a 
digit-grouping space in numbers:

Jim, Why do you leave out U+2007 figure space? 
U+2007 FIGURE SPACE is also a non-breaking space.

But Philip Verdy claimed (and I agree) that the digit grouping space in 
numbers should (in a proportional font) be "less wide" than a digit.

U+2007 is by definition the same width as a digit (in a font where there 
is a set of Latin digits with a common width). It represents a space 
used in hard-type technology for leading spaces for numbers in columns 
(sometimes along with U+2008 PUNCTUATION SPACE) to enable right 
justification of numbers in such columns.
