An estimated 281 Mt of crushed stone was produced and shipped for consumption in the United States in the first quarter of 2019, an increase of 13% compared with that of the same period of 2018. The estimated U.S. output of construction sand and gravel produced and shipped for consumption in the first quarter of 2019 was 168 Mt, an increase of 3% compared with that of the same period of 2018. Shipments of portland and blended cement increased slightly in the first quarter of 2019 compared with the first quarter of 2018. This information was obtained from the USGS monthly survey of U.S. cement producers. The estimated production-for-consumption of construction aggregates in the first quarter of 2019 increased in five of the nine geographic divisions compared with that sold or used in the first quarter of 2018. Production-for-consumption increased in 25 of the 39 states that were estimated. The five leading states were, in descending order of pro- duction-for-consumption, Texas, Florida, California, North Carolina and Arizona. Their combined total produc- tion-for-consumption was 155 Mt and increased by 4% when compared with that of the same period of 2018. The estimated production-for-consumption of crushed stone in the first quarter of 2019 increased in six of the nine geo- graphic divisions compared with that sold or used in the first quarter of 2018. Production-for-consumption increased in 28 of the 45 states for which estimates were made. The five leading states were, in descending order of produc- tion-for-consumption, Texas, Florida, North Carolina, Georgia and Pennsylvania. The estimated production-for-consumption of construction sand and gravel in the first quarter of 2019 increased from that of first quarter 2018 in five of the nine geographic divi- sions. Production-for-consumption increased in 22 of the 42 states for which estimates were made. The five leading states were, in descending order of produc- tion-for-consumption, Texas, California, Arizona, Washington and Florida. 2018 Production An estimated 599 Mt of total construction aggregates was produced and shipped for consumption in the fourth quarter of 2018, an increase of 5% compared with that of the same period of 2017, according to Willett. "The estimated annual output of construction aggregates produced for consumption in 2018 was 2.37 billion Gt, an increase of 5% compared with that of 2017," Willett said. An estimated 359 Mt of crushed stone was produced and shipped for consumption in the fourth quarter of 2018, an increase of 5% compared with that of the same period of 2017. The estimated annual output of crushed stone produced for consumption in 2018 was 1.41 Gt, an increase of 4% com- pared with that of 2017. The estimated output of construction sand and gravel pro- duced and shipped for consumption in the fourth quarter of 2018 was 241 Mt, an increase of 4% compared with that of the same period of 2017. The estimated annual output of construction sand and gravel produced for consumption in 2018 was 961 Mt, an increase of 7% compared with that of 2017. The above estimates are based on information reported to the USGS quarterly sample survey of construction aggregates producers in the United States. Shipments of portland and blended cement increased by 2% in the fourth quarter of 2018 compared with the fourth quar- ter of 2017. Annual consumption increased by 3% in 2018, compared with that of 2017. This information is obtained from the USGS monthly survey of U.S. cement producers. The estimated production for consumption of construction aggregates in the fourth quarter of 2018 increased in seven of the nine geographic divisions compared with that sold or used in the fourth quarter of 2017. In the fourth quarter, production for consumption increased in 17 of the 40 states for which production estimates of construction aggregates were made.
