Is poetry usually autobiographical?

I am writing this before reading what others think about the topic.so as  not to copy.
There is no simple answer  to this questionbut on the whole it is not. for me.However poetry is not mathematics and is to a large extent written from a place of deep feeling within;an event, a memory, a sentence,the vision of a sad person in the street… all these can touch the heart.And of course it is not possible to write without some feeling,unless you want to be a postmodern poet akin to th musician writing “60 Seconds” or the artist exhibiting a lavatory bowl.
The  writing in progress  seems to have its own life and demands;furthermore the form the writer chooses will affect what can be contained within it.So although the initial feeling may be based on the writer’s life,the development is not.
Many other things help to create the work;the context of the life of the poet,the culture they came from and now live in,whether they are male or/and female,their reading and education…their interaction with other poets in reading or listening,their loves and hates.Their broader reading and conversations
But it’s a mistake to take poetry as straightforward sharing of someone’s life.Somehow it can seem just as mysterious to the writer as to the reader.Yet poetry has an imprint and it’s easy when one has a bit read to tell Hopkins from Hardy,or Auden from Spender.
It’s a bit like handwriting…we have our unique patterns which is intriguing as we were taught the same way [though now teaching joined up writing is dying out,which says a lot about our culture… if one can call it culture nowadays].

I am not cynical and have much hope for the future.
