Question for any economists reading this.

Are these numbers comparable?

General government consolidated gross debt as a percentage of GDP, from Eurostat.

versus

State and Local Government Spending and Debt in the United States, Amounts in percent GDP, from usgovernmentspending.com.

If they are not, can you suggest sources with comparable numbers, or explain why this isn't the right comparison to be making, etc.?

The basic point is that I'm trying to do direct comparisons of debt/GDP ratios between EU member states on the one hand and US states on the other.

Thanks in advance for any suggestions!
