You can use the following methods to count the total observations by group in SAS:

**Method 1: Count Observations by One Group**

**proc sql;
select var1, count(*) as total_count
from my_data
group by var1;
quit;
**

**Method 2: Count Observations by Multiple Groups**

**proc sql;
select var1, var2, count(*) as total_count
from my_data
group by var1, var2;
quit;**

The following examples show how to use each method with the following dataset in SAS:

**/*create dataset*/
data my_data;
input team $ position $ points;
datalines;
A Guard 15
A Guard 12
A Guard 29
A Forward 13
A Forward 9
A Forward 16
B Guard 25
B Guard 20
C Guard 34
C Forward 19
C Forward 3
C Forward 8
;
run;
/*view dataset*/
proc print data=my_data;**

**Example 1: Count Observations by One Group**

The following code shows how to count the total number of observations by team:

/*count observations by team*/ proc sql; select team, count(*) as total_count from my_data group by team; quit;

From the output we can see that team A contains **6** observations, team B contains **2** observations, and team C contains **4** observations.

**Example 2: Count Observations by Multiple Groups**

The following code shows how to count the total number of observations, grouped by team and position:

/*count observations by team and position*/ proc sql; select team, position, count(*) as total_count from my_data group by team, position; quit;

From the output table we can see:

- A total of
**3**players belong on team A and have a position of Forward. - A total of
**3**players belong on team A and have a position of Guard. - A total of
**2**players belong on team B and have a position of Guard. - A total of
**3**players belong on team C and have a position of Forward. - A total of
**1**player belongs on team A and has a position of Guard.
