我有一个表人员

Name  | Surname  | City | Street | Some Common Field|
A1    |    B1    |  C1  |   S1   |   1             |
A2    |    B2    |  C1  |   S1   |   1             |
A3    |    B3    |  C2  |   S2   |   2             |
A4    |    B4    |  C2  |   S2   |   2             |
A5    |    B5    |  C3  |   S3   |   3             |

我需要结果

Count |City | Street | Some Field|
2     | C1  |   S1   |     1     |
2     | C2  |   S2   |     2     |
1     | C3  |   S3   |     3     |

我怎样才能得到它？
