Duplicative Group Counting

SannaSanna — Tue, 23 Nov 2021 17:40:06 GMT

Hello everyone!

This Forum is just the best for help and hints!

I am trying to produce counts and I am having difficulty trying to figure out the logic to code this scenario. I am trying to count individuals by their age as well as produce counts in their age groupings. I am essentially counting each individual twice (once at their actual age and then again in an age grouping category) My SAS code seem to capture the record once and I cannot figure out a way to count the record twice. Any help or advice would be greatly appreciated. I have included sample data and a results table in which I would like to see the counts. The results table under the Age column will reflect the age of (ID) as well as counted again in the age grouping. For example, ID=SJ990 is counted once under age (12) and then again under age (10-15) under the Count column. Can anyone assist me with figuring out how I can achieve this? Thank you in advance!

Sample Data Table
ID	age	location
SJ990	12	R119
MR213	17	R119
SS913	17	B099
AT893	11	B099
TL332	22	B099

Results Table
Age	Count
11	1
12	1
17	2
22	1
10-15	2
16-22	3

SAS supports this using Multilabel Formats.

Rough idea:

proc format;
value age_mlf_fmt (multilabel)
10 = 10
11 = 11
12 = 12
13 = 13 
....
10-15 = '10 - 15'
16-22 = '16 - 22';
run;

proc tabulate data=have;
class age / mlf;
format age age_mlf_fmt.;
table age;
run;

Tested fully worked exmaple:

Thank you Reeza! Is there a way I can use the aggregated count record rows for further processing? I would like to run further cross tabulations on and want to use the column 'Age' with the aggregated groupings (meaning counting the individuals age as well as counting them again in the aggregated form) to get further results?

I'm not sure what you mean by the second question, but you can use PROC MEANS or TABULATE and save the output to a data set instead of having it displayed if that's what you're asking about. Use the OUT= option on PROC TABULATE or there are a variety of options with PROC MEANS.

proc tabulate data=have out=AGG_SUMMARY;
