Sometimes, these include (or have been proposed to include) restrictions on being in the presence of underage persons (under the age of majority), living in proximity to a school or day care center, owning toys or items targeted towards children, or using the Internet.
Sex offender registries exist in many English-speaking countries, including Australia, Canada, New Zealand, the United States, Trinidad and Tobago, Jamaica, South Africa, the United Kingdom, Israel and the Republic of Ireland.
You can search the entire country through the National Sex Offender Public Website (NSOPW).
Sex offender registries generally include the offender's address, physical appearance, and criminal history.
All fifty states require individuals convicted of certain sex crimes to register.
Those convicted of more violent crimes are typically required to remain registered for a longer period and to update their address more frequently.
Sex offender registration does not exist outside of the English-speaking world, however.
The United States is the only country with a registry that is publicly accessible; all other countries in the English-speaking world have sex offender registries only accessible by law enforcement.
In the United States, the vast majority of the states are applying offense-based registries, leaving the actual risk level of the offender and severity of the offense uncertain. Studies have shown that actuarial risk assessment instruments consistently outperform the offense-based system mandated by federal law.
Consequently, the effectiveness of offense-based registries have been questioned by professionals, and evidence exists suggesting that such registries are counterproductive.
Like the Australian and British registers, the New Zealand sex offenders register will not be accessible to the general public but only to officials with security clearance.
It will also include individuals who have been granted name suppression.
Authorized police use ANCOR to monitor persons convicted of child sex offences and other specified offences once they have served their sentence.
