Nationally most jobs and most wages are at big companies (over 500 employees). 52% of all jobs and 58% of all wages in the USA are from big companies. But of course it varies by state. In Montana only 32% of jobs are from big companies and its 59% in Nevada. Montana again has the lowest wages from big companies at 39% and at the other end Georgia has the most wages at 62%.
I found data on employment based on firm size data on the SBA website. Specifically : Table 1- Number of firms, establishments, employment, and payroll by firm size, state, and industry
