Here are some interesting figures about Venice take from this recent FT article by Chris Allnutt:
Tourist visits to Venice last year were estimated to be about 1/5 of what they usually are
Short-term rental bookings as of December 2020 were down about 74% year-over-year
It is estimated that short-term rentals normally represent about 12% of homes in Venice (this is significantly higher than the "typical city" which is estimated to be about 1-2%)
Even before the pandemic, average property prices had declined from about €4,500 per square meter in 2018 to €4,341 in 2019 (2020 data is still coming)
Pre-pandemic, the population of the city was about 50,000, which is less than a third of what it was back in the 1950s
A 2018 study by Airbnb reported that for every local Venetian the city had 74 tourists on average (wow)
Being a dominant port city, the city has generally been disproportionately impacted by plagues and other health crises throughout its history
The Lazzaretto Vecchio, which still stands today, is a small island in the Venetian Lagoon that was founded in the 15th century as a hospital to care for plague victims; apparently it was the first of its kind in the world
During the 15th century, Venice saw its population drop by about two-thirds as a result of an epidemic
At the height of the Republic of Venice in the 1790s, the city had a population of about 170,000; after falling to Napoleon it halved to about 96,000
It's worth pointing out that the "height of the republic" occurred after many great epidemics; the subsequent population decline was seemingly the result of a conquest and not pestilence

Venice has been keeping flood records for 150 years, though it is generally understood that the city has been regularly flooding since the very beginning. It usually happens between the fall and the spring and the earliest record is believed to be from the 6th century.
This past week, Venice saw its acqua alta (or high water) peak at 187cm (6'2") above its normal level. This is the second highest number on record and is just below its 1966 peak. At these numbers, about 80% of the historic center is underwater. Here is a chart from the WSJ explaining that:
Venice has been working on a flood management project called MOSE since the 1980s. The name is an acronym, but there's a deliberate biblical reference here. Remember when Moses parted the red sea?
The project has been mired in engineering delays and corruption scandals, and so it's not yet operational. If it were, it would have, in theory, protected the city this past week. 2022 is the anticipated completion date, but I don't know if that's realistic or not.
The system consists of 78 mobile gates that fill with water and sit flat on the seabed when the tide is low. When a high tide is predicted, the gates are then to be pumped with air so that they rise (hinged on one side) and close off the three inlets that connect the Venetian Lagoon to the Adriatic Sea.
As I was reading about this project and everything else that has been going on in Venice this past week, I became curious about how exactly the Dutch have been managing to hold back the sea. I mean, a big chunk of the Netherlands sits below sea level.
If you're also curious, here's a video that explains how they do it.
