For each of the years ended September 30, 2018, our total revenue was derived from the following customers:

During fiscal year 2018, the U.S. Federal Government, the U.K. Government, the Australia Government and the State of New York each provided more than 10% of our annual revenue. Within these governments, we may be serving several distinct agencies. Revenue from the U.S. Federal Government was exclusively within the U.S. Federal Segment. Revenue from the U.K. Government was both within the Health Services and Human Services Segments. Revenue from the State of New York was exclusively within our Health Services Segment. Revenue from the Australian Government was exclusively within our Human Services Segment. The proportion of revenue recognized from customers providing in excess of 10% of our consolidated revenue for each of the three years ended September 30, 2018, was as follows:
