st:combining datasets

[Kenisha Russell <kenisha.russell@framtidsstudier.se>]

Hi All, 
Can someone please help me to solve the issue I am having with combining my datasets. 
Take for example, that I have the following three data sets.

Dataset 1
ID	year	month	educ	age
A	2005	8	Secondary 	21
A	2005	9	Secondary	21
A	2005	10	Secondary	21
A	2005	11	Secondary	21
A	2005	12	Secondary	21
A	2006	1	Secondary	22
A	2006	2	Secondary	22

Dataset 2
ID	Reg_year	Reg_month	Reg_day
A	2002	8	1

Dataset 3
ID          status-year         status_ month	status_ day	emp_status
A	2005	9	3	internship
A	2006	2	1	employed


What I would like to do is create one  large dataset organized as below, so I would appreciate any ideas and or suggestions on how to do this. 

ID	year	month	educ	Reg_year	Reg_month	Reg_day   status_year  status_ month  status__ day    emp_status
A	.	.	.	2002	8	1	.	.	.	.
A	2005	8	Secondary 				.	.	.	.
A	2005	9	Secondary				2005	9	3	internship
A	2005	10	Secondary				.	.	.	.
A	2005	11	Secondary				.	.	.	.
A	2005	12	Secondary				.	.	.	.
A	2006	1	Secondary				.	.	.	.
A	2006	2	Secondary				2006	2	1	employed

Thanks for your time and advice beforehand.
