We are working on an methodology, allowing to detect disparities between the regions and within/inside the regions. For example:

• There is a two-fold difference in salary between region A and B - this is a between region disparity.

• Only 2% of residents receive a median salary in region D - this is a within/inside region disparity.

Does the following sentence, using words between and within carry the same message:

Novel methodology for identifying between and within region disparities in income

Or should I use other words?
