The revised estimated annual output produced for consumption in 2016 was 2.30 billion metric tons (Gt), a slight increase compared with the annual output for 2015. This was previ- ously reported as 2.33 Gt An estimated 261 Mt of crushed stone was produced and shipped for consumption in the United States in the first quarter of 2017, a slight decrease compared with that of the same period of 2016. The revised estimated annual output produced for consumption in 2016 was 1.36 Gt, a slight increase compared with that of 2015. This was previously reported as 1.37 Gt. The estimated U.S. output of construction sand and gravel produced and shipped for consumption in the first quarter of 2017 was 165 Mt, a decrease of 4 percent compared with that of the same period of 2016. The revised estimated annual output produced for consumption in 2016 was 945 Mt, a slight increase compared with the annual output for 2015. This was previously reported as 959 Mt. The above estimates are based on information reported to the U.S. Geological Survey (USGS) on its quarterly sample survey by construction aggregates producers. Previously reported data are occasionally revised, and the estimated quantities for the prior quarters are then recalculated. Shipments of portland and blended cement increased slightly in the first quarter of 2017 compared with the first quarter of 2016. Annual consumption increased slightly in 2016, com- pared with that of 2015. This information is obtained from the USGS monthly survey of U.S. cement producers. The estimated production-for-consumption of construction aggregates in the first quarter of 2017 decreased in five of the nine geographic divisions compared with that sold or used in the first quarter of 2016. The largest decrease in percentage was recorded in the West North Central division. Production-for-consumption increased in 26 of the 43 states for which estimates were made. The five leading states were, in descending order of production-for-consumption, Texas, Florida, California, Georgia and North Carolina. Their com- bined total production-for-consumption was 138 Mt and increased by 3 percent when compared with that of the same period of 2016. The estimated production-for-consumption of crushed stone in the first quarter of 2017 decreased in five of the nine geo- graphic divisions compared with that sold or used in the first quarter of 2016. The largest decreases in percentages were recorded in the New England, the Pacific and the West North Central divisions. Production-for-consumption decreased in 29 of the 46 states for which estimates were made. The five leading states were, in descending order, Texas, Florida, Georgia, North Carolina and Pennsylvania. Their combined total production-for-con- sumption was 95.9 Mt and represented a slight decrease compared with that in the first quarter of 2016. The estimated production-for-consumption of construction sand and gravel in the first quarter of 2017 decreased from that of first quarter 2016 in six of the nine geographic divi- sions. The largest decreases in percentages were recorded in the West North Central, the Middle Atlantic and the East North Central divisions. Production-for-consumption increased in 23 of the 45 states for which estimates were made. The five leading states were, in descending order of production-for-consumption, Texas, California, Arizona, Washington and Colorado. Their combined total produc- tion-for-consumption was 61.6 Mt, which was a 6 percent decrease compared with that in the first quarter of 2016.
