The city has been conducting a citizen survey every other year since 2000 to let residents rate city services and offer input on what the city does well and how it can improve. The current survey is under way and available through Sept. 25 here.

Opinion Dynamics Corp., a polling firm in Waltham, is coordinating the survey and will also randomly call 400 Cambridge residents to complete the survey. Every household in the city with a phone has an equal chance of being called. At least one-quarter of the phone surveys will be conducted with cellphone-only households.

A hard copy of the survey can be done through Sept. 25 at:
