Classifying Similiar States for Income Distribution
I've been playing with different ways to use K-Means classification to find related classes of states when it comes to income distribution. I tried dividing up the states into four groups, which came up some interesting income distributions, as shown below.
| Class | Less than $10,000 | $10,000 to $14,999 | $15,000 to $19,999 | $20,000 to $24,999 | $25,000 to $29,999 | $30,000 to $34,999 | $35,000 to $39,999 | $40,000 to $44,999 |
| Low – 1 | 8 | 5.5 | 5.5 | 5.7 | 5.3 | 5.2 | 4.7 | 4.7 |
| Higher – 2 | 5.5 | 3.7 | 3.3 | 3.3 | 3.2 | 3.4 | 3.1 | 3.2 |
| High – 3 | 4.6 | 3.3 | 3.2 | 3.5 | 3.5 | 3.8 | 3.6 | 3.8 |
| Moderate – 4 | 5.6 | 4.2 | 4.3 | 4.6 | 4.6 | 4.8 | 4.4 | 4.6 |
| Class | $45,000 to $49,999 | $50,000 to $59,999 | $60,000 to $74,999 | $75,000 to $99,999 | $100,000 to $124,999 | $125,000 to $149,999 | $150,000 to $199,999 | $200,000 or more |
| Low – 1 | 4.2 | 8 | 9.8 | 11.9 | 7.9 | 4.8 | 4.6 | 4.3 |
| Higher – 2 | 3 | 6.1 | 8.4 | 12.1 | 10 | 7.4 | 9.9 | 14.3 |
| High – 3 | 3.5 | 7.1 | 10.1 | 13.8 | 10.7 | 7.5 | 8.7 | 9.2 |
| Moderate – 4 | 4.1 | 8.1 | 10.5 | 13.5 | 9.4 | 5.9 | 5.9 | 5.7 |
