This Simple Visualization Compares the Economies of Every U.S. State
This Simple Visualization Compares the Economies of Every U.S. State
Over the previous month, we’ve published simple Voronoi diagrams that visualize the economies of the world as well as $60 trillion of global debt.
This visualization today compares state economies by contribution to America’s GDP of $17.3 trillion (2014), while also grouping the states by geographical regions such as New England, Mideast, Great Lakes, Plains, Rocky Mountains, Far West, Southwest, and Southeast.
Most economic activity is concentrated in three regions: Far West (18.6%), Southeast (21.3%), and Mideast (18.2%). The states in these regions, which cover the majority of the coastline where most big cities are located, comprise nearly 60% of the U.S. total economic output. Compare this with sparsely populated regions such the Rocky Mountains, which contributes only 3.6% of economic output between five large states.
The largest individual state economies include California (13.3%), Texas (9.5%), and New York (8.1%). The smallest economy is held by Vermont (0.2%) with seven others contributing 0.3% of economic output: Maine, Rhode Island, North Dakota, South Dakota, Montana, Wyoming, and Alaska.
How has the relationship between state economies changed over time? The publishers at HowMuch.net note:
“All states have increased their economic outputs between 2011 and 2014, but some have grown faster than others. In terms of regional influence, the Southeast economy has shrunk in relation to other regions by just 0.4% over the last four years, while the Southwest economy has grown by 0.8% relative to other regions. Texas increased the size of its economy by almost $300 billion, more than any other state, growing from 8.8% of the US economy in 2011 to 9.5% in 2014. This growth in Texas was fueled by mining and manufacturing. California grew by just under $300 billion, but only increased its share of the total economy by 0.1%.”

Just 20 Stocks Have Driven S&P 500 Returns So Far in 2023
From Apple to NVIDIA, megacap stocks are fueling S&P 500 returns. The majority of these firms are also investing heavily in AI.

Just 20 Stocks Have Driven Most of S&P 500 Returns
Just 20 firms—mainly AI-related stocks—are propping up the S&P 500 and driving it into positive territory, signaling growing risk in the market.
The above graphic from Truman Du shows which stocks are making up the vast majority of S&P 500 returns amid AI market euphoria and broader market headwinds.
Big Tech Stock Rally
Tech and AI stocks have soared as ChatGPT became a household name in 2023.
The below table shows data from last month, highlighting that just a small collection of companies drove most of the action on the U.S. benchmark index.

1 | Apple | 1.49% | 6.61% |
2 | Microsoft | 1.15% | 5.72% |
3 | NVIDIA | 1.00% | 1.62% |

Microsoft invested $10 billion into OpenAI, the creators of ChatGPT. It has also integrated generative AI into its search engine Bing. This large language model is designed specifically to make search capabilities faster, generate text, and perform other automations.
Also of interest is NVIDIA, which is the most valuable chipmaker in America. It sells $10,000 chips called A100s that allow machine learning models to run. These models perform multiple tasks simultaneously to develop neural networks and train AI systems, including OpenAI’s ChatGPT. Companies that are developing AI-related services, such as chatbots or image generation, may use up to thousands of these chips.
Despite being the world’s most valuable company and a key driver of returns, Apple is an outlier among tech giants with no major projects announced in AI (so far).
Implications of Market Divergence
The problem with the strong gains seen in a few select AI-related stocks is that it clouds wider stock market performance.
Without the AI-led rally, the S&P 500 would be returning -1.4%. as of May 17, 2023.
4. AI is fueling the stock market
A handful of stocks are spearheading the S&P 500's impressive 9% rally this year.
Here’s the kicker: if you excluded AI stocks, the S&P 500 would be down over 1% (according to Societe Generale). pic.twitter.com/SME1mJVpoW

This form of steep divergence, known as market breadth, often signals higher risk in the market.
When more companies experience positive returns it is less risky than a small handful seeing the majority of the gains. Today market breadth is very narrow, and these companies make up over 29% of the entire index’s market capitalization.
How long AI-related firms mask the broader performance of the S&P 500 remains to be seen. A growing number of market pressures, from higher interest rates to banking uncertainty could add further challenges.
