Breastfeeding rates lower in U.K. than USA....why?

Ra
I am from the UK and I have noticed it is very rare here for a mother to breast feed. Especially long term. I would say only around 1-2 mothers in 10 breastfeed. Why is this? I have noticed with this app breastfeeding in USA seems to be the norm where as here it's not. 
Do you agree? Other mums from U.K. Do you find this? 
From polls it seems probably 8-9 mums in 10 breastfeed.
