Hello, everyone.
I'm Nicole LeBoeuf, Assistant Administrator for NOAA's National Ocean Service.
I'm here today to tell you about a collaboration between NOAA and the U.S. Census Bureau
For over 60 years, NOAA's National Geodetic survey has partnered with the Census Bureau
to capture snapshots of our nation's population every ten years when the U.S. Census is conducted.
You see, every ten years, NOAA and the U.S. Census Bureau calculate the center of the population.
This is the location where an imaginary, flat, weightless and rigid map of the United States
would balance perfectly if all Americans were of identical weight.
By using the latitude and longitude information from the Census Bureau,
scientists from NOAA's National Geodetic Survey
precisely locate the center of population at a point on the ground,
designating it as that perfectly balanced location.
Now for the big reveal.
The United States 2020 center of population is located
15 miles northeast of Hartville, Missouri.
Settled in the early 19th century with a population
of 594 citizens as of the 2020 census.
Hartville is the county seat of Wright County, Missouri,
Later this month, the Census Bureau, NOAA,
as well as state and local agencies, will come together for an event to unveil
a geodetic survey mark at the center of population
and present it to the town of Hartville.
Aside from adding a bit of name recognition to a town or city
survey marks like this one are beneficial to the local community.
They're used by land surveyors as a starting point
for many projects that require accurate positioning.
This includes engineering and construction projects from single-family homes to city buildings
and to infrastructure over large areas like roadways,
railways, waterways and electric grids.
NOAA's National Geodetic Survey is key to this partnership
because of their expertise in surveying and mapping and because of their role
in defining and maintaining the National Spatial Reference System.
This system is a huge network of reference points
used every day to support the creation of maps
and any activities that need accurate position
information like when you use your smartphone apps to figure out where you are,
get directions or use any apps that are better informed by knowing your location.
New technologies will continue
to transform how surveying and mapping is conducted and will play a key role
as NOAA modernizes the National Spatial Reference System.
This decades-long endeavor will reduce our reliance on using geodetic marks on the ground
to using Global Positioning System or GPS,
as well as other global navigation satellite systems and more.
Using GPS stations that continuously collect data
will provide our scientists with up to date information to help them measure,
monitor and better understand the physical
and geometric properties of the Earth.
Because the Earth's surface is pretty much always changing shape
when we use physical survey marks like the one will be installing in Hartville,
surveyors may need to return to that place and obtain new measurements over time.
Although it might be a good reason to get back to Missouri,
modernizing the system will save time and money for everyone who conducts surveying and mapping.
That said,
as we continue to use and even depend on newer technology,
we still need ways to easily check our work and make sure the data is correct.
Survey markers in the ground provide us with this information, and even though we've been using them
for a very long time, they will remain important for surveying
and mapping in the future.
Although many of us might not think about surveying and mapping,
very often, it touches so many parts of our daily lives.

I'm excited for what the future holds, continuing to work
with other federal agencies, modernizing the National Spatial Reference System
and providing information essential to serving the needs of our nation every day.
Thank you.
