Question: What is the population of the state which has its eastern border defined by the 25th meridian of longitude west from Washington?

Context paragraphs:
180th meridian: The 180th meridian or antimeridian is the meridian 180° east or west of the Prime Meridian, with which it forms a great circle dividing the earth into the Western and Eastern Hemispheres.  It is common to both east longitude and west longitude.  It is used as the basis for the International Date Line because it mostly passes through the open waters of the Pacific Ocean.  However, the meridian passes through Russia and Fiji as well as Antarctica.

Prime meridian: A prime meridian is a meridian (a line of longitude) in a geographical coordinate system at which longitude is defined to be 0°.  Together, a prime meridian and its antimeridian (the 180th meridian in a 360°-system) form a great circle.  This great circle divides the sphere, e.g., the Earth, into two hemispheres.  If one uses directions of East and West from a defined prime meridian, then they can be called Eastern Hemisphere and Western Hemisphere.

Bombay Time: Bombay Time was one of the two official time zones established in British India in 1884.  The time zone was established during the International Meridian Conference held at Washington, D.C in the United States in 1884.  It was then decided that India would have two time zones, with Calcutta (now Kolkata) using the 90th meridian east and Bombay (now Mumbai) the 75th meridian east.  Bombay Time was set at 4 hours and 51 minutes ahead of Greenwich Mean Time (GMT).

32nd meridian west from Washington: The 32nd meridian of longitude west from Washington is a line of longitude approximately 109°02′48″ west of the Prime Meridian of Greenwich.  In the United States of America, the meridian 32 degrees west of the Washington Meridian defines the western boundaries of the State of Colorado and the State of New Mexico and the eastern boundaries of the State of Utah and the State of Arizona.

25th meridian west from Washington: The 25th meridian of longitude west from Washington is a line of longitude approximately 102.05 degrees west of the Prime Meridian of Greenwich.  In the United States of America, the meridian 25 degrees west of the Washington Meridian defines the eastern boundary of the State of Colorado, the western boundary of the State of Kansas, and the western boundary of the State of Nebraska south of the 41st parallel north.

Colorado: Colorado ( ) is a state in the United States encompassing most of the Southern Rocky Mountains as well as the northeastern portion of the Colorado Plateau and the western edge of the Great Plains.  Colorado is part of the Western United States, the Southwestern United States, and the Mountain States.  Colorado is the 8th most extensive and the 21st most populous of the 50 United States.  The United States Census Bureau estimates that the population of Colorado was 5,540,545 on July 1, 2016, an increase of 10.17% since the 2010 United States Census.

Western Australia border: The Western Australian border was originally designated as 129th meridian east longitude (129° east).  However, the border marked on the ground is some distance from this line.  Kununurra is the closest town to the Western Australian border, being about 25 km west of the border.  The closest settlement is Border Village, 1,734 km to the south on the South Australian side of the border, on Eyre Highway.

2009–10 Australian region cyclone season: The 2009–10 Australian region cyclone season was a below average tropical cyclone season, with eight tropical cyclones forming compared to an average of 12.  The season began on 1 November 2009 and ran through until it end on 30 April 2010.  The Australian region is defined as being to south of the equator, between the 90th meridian east and 160th meridian east.  Tropical cyclones in this area are monitored by five Tropical Cyclone Warning Centres (TCWC's): Jakarta, Port Moresby, Perth, Darwin, and Brisbane, each of which have the power to name a tropical cyclone.  The TCWC's in Perth, Darwin, and Brisbane are run by the Australian Bureau of Meteorology, who designate significant tropical lows with a number and the U suffix.  The Joint Typhoon Warning Center also issues unofficial warnings for the region, designating significant tropical cyclones with the "S" suffix when they form west of 135°E, and the "P" suffix when they form east of 135°E.

Fifth principal meridian: The Fifth principal meridian, often denoted the "5th Meridian" or "PM 05," is a principal meridian survey line used in the United States for land claims in the Public Land Survey System (PLSS).  It was first surveyed in 1815.  The meridian, a north-south line, starts from the old mouth of the Arkansas River and runs north.  Another survey line related to it is the base line running west from the old mouth of the St. Francis River.  These survey lines govern all land surveys in four states and a large portion of the land surveys for two more.  Monuments have been erected where the two lines meet at , and the surveyors' skill has been commemorated at the Louisiana Purchase State Park in eastern Arkansas.  The Fifth principal meridian is nearly coincident with 91° 3′ 42″ longitude west from the Greenwich meridian.

2010–11 Australian region cyclone season: The 2010–11 Australian region cyclone season was a near average tropical cyclone season, with eleven tropical cyclones forming compared to an average of 12.  The season began on 1 November 2010 and ended on 30 April 2011, although the first tropical cyclone formed on 28 October.  The Australian region is defined as being to the south of the equator, between the 90th meridian east and 160th meridian east.  Tropical cyclones in this area are monitored by five Tropical Cyclone Warning Centres (TCWC's): Jakarta, Port Moresby, Perth, Darwin, and Brisbane, each of which have the power to name a tropical cyclone.  The TCWC's in Perth, Darwin, and Brisbane are run by the Bureau of Meteorology, who designate significant tropical lows with a number and the U suffix.  The Joint Typhoon Warning Center also issues unofficial warnings for the region, designating significant tropical cyclones with the "S" suffix when they form west of 135°E, and the "P" suffix when they form east of 135°E.
