It is also been shown through research that children born to poor parents are likely to have reduced weight and height at birth, are less likely to excel academically and have poorer attendance records in school. Adults who grew up in poverty are more prone to ill-health, unemployment, homelessness, arrests for criminal offences, drug and alcohol abuse and abusive relationships. It is often the case that children in poverty stay in poverty well into their adult life as well and remain in the same quarter of income distribution as their parents. Some of the main reasons why children fail to break this cycle of poverty are missing periods of school, being in care, being known to police, misuse of drugs, teenage parenthood and being out of education either having to work or otherwise.
