칼럼명 설명
- 주민번호 : jumin
- 성별 : sex_name (1:남자,2:여자)
- 나이대 : age_name (20:20대미만, 25:21살~25살, 30:26살~30살...)
- 회원수 : total_count

asp 페이지에서
 연령대  성별합  남자  여자
 20살미만  100,000  50,000  50,000
 21살~25살      
 26살~30살      
 31살~35살      
 ....      
 61세이상      

머 이런식으로 사용하면 됨.
참고로 각 수치옆에 (%)로 해주면 더 좋겠죠?
asp 단에서 처리할 내용이 많을듯.
