sample a similar population?

[SASguyCO]

I'm not sure this is the correct forum so please someone point me in the right direction if it's not.

I have one population that is distributed a certain way by length of tenure and I'd like to sample from another population such that I end up with the same distribution. 

For example I have pop A summarized as follows:

                 %    

tenure 1    10

tenure 2    30

tenure 3    25

tenure 4    35

and I'd like to randomly sample from pop B (say, 1,000,000 records) so that the 4 tenure buckets distribute just like pop A above so I'd have:

Pop B       N

tenure 1   100,000

tenure 2   300,000

tenure 3   250,000

tenure 4   350,000

I imagine there has to be some sort of statistical/sampling PROC to achieve this? If not, perhaps some basic code?

thanks a ton for any assistance!

proc surveyselect with SAMPRATE option.

Thank you Reeza, can you please provide sample syntax of how this would be accomplished with PROC SURVEYSELECT?  I've looked at the documentation and it seems pretty complex.
