How Much Does Each State Rock?

HMDESRStone, sand and gravel are items every American uses in their daily life, whether they know it or not. A new map shows how much aggregate is produced in each state. It also shows the number of mines and people it takes to produce these essential building materials, compiled by the National Stone, Sand & Gravel Association (NSSGA).

Many uses of aggregates are easy to see in our homes, towns and cities and in the asphalt and concrete in our roads and bridges. Yet, pulverized limestone is used in toothpaste and aggregates are key ingredients in everyday products like paper, glass and medicines. “It has been estimated that every American will need about 1.18 million pounds of stone, sand and gravel in their lifetimes,” said Michael W. Johnson, NSSGA president and CEO. “Aggregates aren’t just found in roads and bridges. They make up the concrete in our foundations, the shingles on the roof and everywhere in between, like the wallboard, tile, glass and plaster.”

The aggregates map shows the impact these operations have by producing the building blocks of our infrastructure at www.nssga.org/education/research-map.
