According to 2010-2013 U.S. Census data compiled by local real estate firm Paragon, (you may have seen their signs in front of some expensive houses for sale) the zip code with the highest median income in San Francisco is 94105, which encompasses parts of SoMa including Yerba Buena and South Beach.

Perhaps unsurprisingly, the 94105 ranked last for average household size, meaning there are a lot of high-paid childless people living in SoMa these days. St. Francis Wood/Miraloma in the 94127 had the second highest median income, followed by the Presidio at number three.

While the real estate firm was digging into the census data, they also sorted the zip codes by median age, only to discover the median age on Treasure Island is a mere 28 years old. The 94111 zip code along the city's Northern Waterfront and a sliver of Telegraph Hill, meanwhile, was practically ancient with the highest median age of 50 years old.

Here's a heartwarming statistic dredged up from Facebook's data mines: San Franciscans are the least likely people in the country to commit to a relationship. (Or commit to updating their relationship status, at least.)

The information comes from the company's own Valentine's Day trends report, which looked at the percentage of single people in the top 50 cities in the country and the rate at which people pair off. Apparently if you wanted to settle down, you should have moved to Colorado Springs, which has the lowest percentage of single people and the highest rate of "relationship formation" in the country. We can only assume this has something to do with keeping warm in those Rocky Mountain winters.

Closer to home though, Facebook analyzed check-ins at local businesses to determine which ones get busier in the week before Valentine's Day. Topping the list is noted Marina bar Stock & Trade, where local straight ladies will probably have an easy pick from the San Francisco sausagefest. The report also confirmed what any single person in town already knows: that the city has the highest ratio of single males to single females.

It's all relative, as the saying goes, and it's never been truer than with today's announcement that San Francisco has been crowned the "most bike-friendly city" in the nation. Or, as it could be called, the "most non-shitty" place to ride a bike around town.

The finding are based on data collected from the Alliance for Biking and Walking, and compiled by Statista, which found that, with 5.6 miles of dedicated bike lanes, multi-use bike paths and signed bike routes per square mile (263 miles in total), we've got the best biking infrastructure in the country.

Not taken into consideration? The cycling accidents and fatalities that have plagued the City in recent months; although it remains unclear how the City's bike accidents per capita stack up against the other cities listed in the top ten, which include Austin, Long Beach, and Philadelphia (Portland, a longtime West Coast rival for urban bikeability, is noticeably absent from the list).

Which makes us wonder: Statistically speaking, San Francisco may be the most bike-friendly city in the nation, but what does it feel like? Ladies and gentleman, to better understand your deep-seated emotions about the issue, we present a rare SFist poll. Fire away, citizens.

Want to see to what certain SF public officials are landing a year? Of course you do. Business Insider came across a handy chart (based on this database) that lists the yearly salaries of public servants. the info is from a couple of years ago -- thus: yes, it's old news -- but since we cannot digest any info that isn't crafted into easy-to-read cells, we assume the same goes for you, readers.

A few things to note:

• SFFD Captain Edward Arce makes nearly $20,000 more a year than Joanne Hayes-White.

• SFMTA executive director Nat Ford is making $300k+ a year. Of course.

• There are three cops making more than habitual police chief Heather Fong. Why? (Besides the obvious, that is.)

• These numbers are from the 2007 calendar year. The data was provided by the City of San Francisco's Controller's Office, which includes regular pay, overtime and "other pay," i..e., "compensation for special working conditions or one-time pay-outs of unused vacation and sick leave to employees leaving the city."

• How can we land over $200K worth of overtime, Christian Kitchen?

• More cuts can be made, Arnold.

For all you real estate data wonks and renters who like to feel smug: the median price of homes sold in the nine-county Bay Area is down 41% over last year, to $304,000. This also marks a pretty steep fall from the peak median price of July 2007 which was $665,000.

Median price figures are not the clearest indicators, though, because they only reflect on properties currently on the market to be sold. In shitty markets like this one, owners in high-end properties tend not to sell, thereby skewing median prices down due to unusually low numbers of sales at the high end. This is coupled with averaging in the worst market in the region, Solano County, where a rock bottom median of $180,000 is causing an uptick in sales, with people scooping up low-priced homes fast, often as investment properties. The median price in San Francisco is still $628,500, down 16% over last year. See all the county figures after the jump, and read DataQuick's analysis here.
