Since 2011, there have been 118,352 instances of human waste being reported
Last year the number hit an all time high with more than 28,000 cases
The number is five times the amount that was reported eight years ago
San Francisco's homeless crisis has been well documented for several years
An interactive map marking every spot in San Francisco where human waste has been reported over the last eight years has emerged as the city continues to grapple with its growing homeless population.
The staggering map pin points every location where human waste has been reported since 2011.
The result is a blanket of brown pins which almost covers the city entirely.
In total, there have been 118,352 instances reported over the last eight years.
Most were found in one of ten neighborhoods; Tenderloin, South of Market, Mission, Civic Center, Mission Dolores, Lower Nob Hill, Potrero Hill, Showplace Square, North Beach and the Financial District.
Their data revealed that the worst year was last year when more than 28,000 instances were reported.
The number was 8,000 more than the previous year and more than five times the 5,547 that were reported in 2011.
San Francisco's homeless problem has been a talking point among local media, industry and residents for years.
It has been dubbed the 'shame of the city' and been likened to a human rights crisis by UN investigators.
The incidents took place mostly in 10 neighborhoods stretched out across the northern part of the city
Over the last eight years, the numbers have increased and are now five times where they were in 2011
In the last eight years, the number has increased gradually and is now five times the number it was in 2011
It is caused by a combination of factors.
While there are technically no more homeless people there than in other cities across the US like New York or Los Angeles, San Francisco is far less spread out, meaning the homeless population is more dense.
What's more, there are fewer shelter options than in other major cities.
The lack of shelters in the excruciatingly expensive city mean thousands of homeless people have no choice but to sleep on the streets, often in tents.
It has created a permanent tension among residents, many of whom work in Silicon Valley and have spent millions buying property there.
The feces issue has been well-documented in the past by other researchers.
Last year, as tensions reached fever pitch, some homeless people started using their own waste as material to slather graffiti on the walls and streets of the city.
