Social work has its roots in the social and economic upheaval brought by the Industrial Revolution, in particular the struggle of society to deal with poverty and  its resultant problems. Because dealing with poverty was the main focus of early social work, it is intricately linked with the idea of charity work, but it must now be understood in much broader terms. For instance it is not uncommon for modern social workers to find themselves dealing with the consequences arising from many other 'social problems' such as racism, sexism, homophobia, and discrimination based on age or on physical or mental ability. Modern social workers can be found helping to deal with the consequences of these and many other  social maladies in all areas of the human services and in many other fields besides.
