>>> Over the last decade the violent crime rate has steadily dropped.
>>> For the last twelve years I have live

We can use present perfect ( progressive / continuous ) tense as follow:
Present perfect ( progressive / continuous ) ..... since + point of time
1 I have known him since 1995.
2 I haven't seen her since Friday.
3 I have been living in London since I was born.
Present perfect ( progressive / continuous ) ..... for + du
Present perfect ( progressive / continuous ) ..... since + point of time
1 I have known him since 1995.
2 I haven't seen her since Friday.
3 I have been living in London since I was born.
Present perfect ( progressive / continuous ) ..... for + du
