I'm writing a book set in Victorian England, circa 1850. I have a few questions about currency value, prices, and child labor.

I tried Google, but I need more definitive answers than the ones I've found so far.

1: What were prices like compared to 2017? For example, how much did a 500ml bottle of very low-end whiskey cost? What about the average loaf of bread? Basically, how many 1850 pounds would you need to feed the average Victorian man? What is that in 2017 pounds? Did prices inflate in a linear fashion? Is there a way to calculate prices from 1850 to 2017?

2: I'm told Soho had relatively cheap housing during that time. If so, what was the average monthly rent for a shitty apartment (use 1850 pounds)? Is there a cheaper area, or was Soho the lowest?

3: Were younger teens (12-15) often employed by small businesses, or were adults preferred? If children were employed, were they paid less?

4: What were rare luxuries back then? As in, if you saw someone eating caviar today, you'd think they were rich, so what would be a sign of wealth in the 1850's?

5: What was the average prostitute's rate? And... uh... were there child and teen prostitutes?

6: What was the average tuition for a London medical school? How much did they know about anatomy? Finally, did they know about the spinal cord and arteries? Was the average doctor aware that cutting the jugular could mean death?
