The Decline of Deer Populations
     The total U.S.deer population in 2017 was about 33.5 million, up from a recent low of about 32.2 million in 2014, down from the recent peak in 2000 of about 38.1 million deer.  The whitetail population fell from about 33.5 million in 2000 to 28.6 million in 2014, recovering to about 29.5 million in 2017.  The mule, blacktail, and other deer populations fell from about 4.6 million in 2000 to about 3.6 million in 2014, recovering to about 4 million in 2017.  The recent peak for mule and blacktails was around 1960, illustrated in the graph below for the estimated U.S. deer population from 1450 to 2017.

     Deer were nearly hunted to extinction by the early 1900s and were extirpated in many regions.  Conservation and restocking allowed whitetail populations to recover to about pre-colonization levels while blacktails and mule deer are below historic levels.
    A Wall Street Journal article recently reports that “The U.S. now has 30 million deer, a hundred times more than a century ago" failing to point out that deer faced a near extinction event 100 years ago and that the white-tail population has approximately returned to its historic population size.  The modern decline of mule and blacktail populations has been a major concern of wildlife agencies for decades.
     The population estimate [methodology] is based on information from state agencies and other groups collected on this website, discussed on each state page that can be accessed by clicking on the drop down menus above.  The estimate also relies on harvest data for each state, available using the links at the top of the column at right.  A few numbers are unavailable and estimated.  

     As illustrated in the figure above, the U.S. deer harvest fell by 14.7 percent from 2000 to 2017, from about 7.5 million to 6.4 million.  Mild winters in the north and recovery from the Texas drought account for much of the uptick since 2014. The Western Association of Fish and Wildlife Agencies estimates the total U.S. mule and blacktail deer population at 4 million in 2015 and 4.2 million for 2016 - 2018.  Some numbers are goals, so population estimates from these states have been adjusted based on harvest data.  Detail.
     Data for the trend in the white-tailed deer population from 2000 and earlier is based on Kert VerCauteren in The Deer Boom and the Wildlife Management Institute's 1984 book "Whitetail Deer Ecology and Management", updated using current harvest data and state population estimates.  Recent University of Wyoming research puts the white-tailed deer population prior to European settlement at 30 to 40 million, so the estimate above may be low.  A summary of historic mule and blacktail population estimates. 
     Research published in 2014 and 2016 [PDF] using data from this site identified the recent change in the total population trend, turning down around the year 2000.
Causes for the Decline of the Deer Population
    Habitat loss, change, and fragmentation are known to play a role in the decline.  Many fear that chronic wasting disease will drive the deer population to low levels over the coming decades.
     Searching the internet, this site has tracked many of the proposed causes for the declining deer population reported in the column at right and in more detail on for each state on their page, including:
-  Maine and New England:   Changes that have occurred on commercially managed forest lands – based on a new Forest Study
-  Connecticut:  First decline since early 1900’s, increased predation  (Bobcat, Coywolf)
-  Western North Carolina:  Mature Forests, Cherokee Indians are restocking deer herds
-  West Virginia:  Aging forests in high mountains
-  Georgia:  Coyotes
-  Minnesota:  Severe Winters
-  Illinois, Iowa, Michigan, and Minnesota:  Overharvest, drought, EHD
-  Colorado:  Food supply, predation, energy development
-  North Dakota:  Drought, EHD (severe decline), habitat loss
-  Montana:  Loss of habitat, severe winter, predation
-  Oregon:  Reduction in logging related to timber sales

      The map below illustrates the 2013 harvest as a percent of peak harvest. The deepest declines, in red, appear in western states where the mule and blacktail deer reside.
Elk populations, once exceeding 10 million in the continental United States, number about 1 million.

Mule Deer and Blacktail Deer Populations Have
 Been in Decline for Many Years

The graph below shows the estimated 1911 to 2016 California deer population, made up of blacktails and mule deer, falling by about 75 percent from 1960. See the California page for an analysis of what appears to be the largest modern decline in the deer population. 

Read a peer reviewed research article demonstrating how public management decisions in California may have contributed to the long term decline of the deer population.

Seasonal neighbors: residential development encroaches on mule deer winter range in central Oregon March 27, 2012 Oregon, U.S. Forest Service Pacific Northwest Research Station, Marie Oliver
Mule deer populations in central Oregon are in decline, largely because of habitat loss. Several factors are likely contributors. Encroaching juniper and invasive cheatgrass are replacing deer forage with high nutritional value, such as bitterbrush and sagebrush. Fire suppression and reduced timber harvests mean fewer acres of early successional forest, which also offer forage opportunities. Human development, including homes and roads, is another factor. It is this one that scientists with the Pacific Northwest Research Station and their collaborators investigated in a recent study. ..

From Wildlife.Utah.Gov: "Since 1922, the Western Association of Fish and Wildlife Agencies (WAFWA) has served as a leader promoting management and protection of fish and wildlife in the western United States and Canada. An organization represented by 17 states and four Canadian provinces, WAFWA has faced the difficult challenge of sifting through the ever-changing societal, economic, political and scientific issues that define natural resource management in a West that has undergone many changes. WAFWA is particularly concerned about mule deer, a species that lives in every North American habitat except for the tropics, arctic and extreme deserts. Mule deer numbers and distribution have been declining throughout the West since the latter third of the 20th century. To address this concern, the Mule Deer Working Group was established at the midwinter meeting of WAFWA in 1998. The group was charged with finding “solutions to our common mule deer management problems,” expanding “cooperative research and management in the Western states and provinces,” and sharing information with agency directors and administrators on mule deer issues."

Study of the Reasons for the Decline of Nevada's Deer Population: MULE DEER INITIATIVE Commission Briefing - February 20, 2009, (Oregon). Issue: Researchers and wildlife managers generally concede mule deer achieved maximum abundance during the 1950s and ‘60s. Since then, mule deer have declined across the West, including Oregon. The most recent decline appened during the early 1990s and, though not fully understood, it is believed to be primarily due to the combined effects of drought and severe winters. Historically, deer populations rebounded quickly after such climatic extremes. However, in recent years, production and survival of fawns have remained at depressed levels. Low recruitment, severe winters, dry summers, changing predator/prey relationships, and increased habitat loss have pushed mule deer populations lower than the department and public desire.
