If an A is outstanding and a C simply average, how would you grade San Francisco's city services?

The biennial city survey attempts to do just that. The 2019 survey, released Monday by the City Controller's Office, is the culmination of more than 2,200 phone interviews with San Franciscans (you can read more about it on The Chronicle's website).

The survey rated everything from the city's parks and safety to 311 services and infrastructure. Not a single service was graded, on average, lower than a C, though public transit came close with a C+ rating — the lowest grade of the seven categories.

The highest grade did not go to the city's famous parks — or its progressive government. It went to the library, the sole service to receive an A-. Its ranking increased by a half-grade since 2017, the last time the survey was conducted.

Survey respondents — 51 percent of whom were white, 22 percent Asian or Pacific Islander, 12 percent Latino, 9 percent other and 5 percent black — were also asked what they believed to be the "top issues" facing San Francisco. The No. 1 answer was, unsurprisingly, homelessness, which 75 percent said had gotten worse since 2017.

Fifty-five percent of respondents made over $100,001 annually.

Other top issues were infrastructure and public safety. A near-majority of survey takers believed both issues have worsened since 2017, citing factors like trash and bodily fluids on the sidewalk and petty crime, like bike theft and car break-ins.
