The Museums Association has launched Museums Change Lives  which is a vision for the increased social impact of museums.  Having worked with all sorts of museums for many years, we know that museums do have a positive impact on individuals and communities, so it's good that this aspect is getting more attention.

More recent developments are museums' impacts on people's health and well-being, and environmental sustainability.

Museums need to continue to demonstrate their value (not just in monetary terms!) and for this, they need to record and measure what they do, and keep up with their visitors' opinions.
