Reply to comment by timf5758 in [OC] Prices for common food products, August 2010 vs 2022. by robert_ritz

There are ups and downs, but the recent inflationary pressures are the cause of most of the increase.

Check out the meat price time series here: https://www.datafantic.com/content/images/size/w1600/2022/10/meat.png

And some fruits here and here.

The full time graphs you posted in this comment are much more interesting than 2 time points 12 years apart, can see much more clearly when the increases happen

I never realized how much seasonal variation there is on the price of strawberries and grapes. Like, I understood there was seasonal variation but I vastly underestimated how big the swings were.

As a strawberry/grape fan who lives in the northern Rockies (USA), I am accutely aware of the seasonal variability in prices.

Stonefruits are also highly variable here. Plums can range from $1-$3.50/lb

This subreddit is a fickle mistress. I totally agree that the time series is more interesting.

If you need to refer us to external sources for your data, what is the point of making that ridiculous graph?

Because sometimes one chart doesn’t tell the whole story.

This graph can be misleading a 5% increase in bacon will look significantly larger than a 5% increase in rice

Hence the term slope. The slope of the line tells you the rate of change.

Slope will look different 2 to 3 dollars is 50% 4 to 6 is 50% bigger difference the slope portrays a 20 cent change the same, but not a 20% change

In percent terms true. I’ll add that chart to the blog post I think.

Alas I can only post one chart at a time here.
