Horses serve an extraordinary range of purposes in the modern world, from competitive sport and therapy to law enforcement, agriculture, and pharmaceutical production. With roughly 60.8 million horses worldwide according to 2023 FAO data, the species remains deeply woven into economies, cultures, and daily life across dozens of countries. In the United States alone, the horse industry contributes $177 billion to the economy and supports 2.2 million jobs.
Racing and Competitive Sport
Horse racing is the most financially significant use of horses globally, generating an estimated $115 billion in annual revenue. The Kentucky Derby alone attracts over $1 billion in wagers each year, and in Japan, more than $10 billion is bet annually on horse racing. The industry supports massive networks of breeders, trainers, jockeys, veterinarians, and facility workers.
Beyond racing, competitive equestrian sport spans several distinct disciplines. The Olympic program includes three: dressage, jumping, and eventing. Dressage tests a horse’s precision, balance, and responsiveness through choreographed movements. Jumping challenges horse and rider to clear a course of obstacles up to 130 centimeters high at speed. Eventing is considered the most demanding, combining all three phases: a dressage test, a cross-country course that can stretch nearly 6 kilometers with up to 42 jumping efforts, and a stadium jumping round. Outside the Olympics, horses compete in polo, endurance racing, barrel racing, reining, and dozens of other disciplines shaped by regional traditions.
Therapy and Rehabilitation
One of the fastest-growing uses for horses is in therapeutic settings. Hippotherapy, a form of physical, occupational, and speech therapy conducted on horseback, is used to treat people with cerebral palsy, autism, multiple sclerosis, traumatic brain injuries, stroke recovery, spinal cord injuries, and psychiatric disorders including eating disorders and trauma from abuse.
The therapy works because of a simple biomechanical fact: a walking horse moves its pelvis in a three-dimensional pattern that closely mimics the motion of a human pelvis during walking. This rhythmic, repetitive movement delivers motor and sensory input to the rider’s body, stimulating the musculoskeletal, vestibular (balance), and sensory processing systems simultaneously. For someone with cerebral palsy or a spinal cord injury, this input helps develop the muscles along the spine and improves coordination in ways that are difficult to replicate in a clinic. Parents of autistic children in hippotherapy programs frequently report improvements in physical ability, social engagement, and sensory function.
Law Enforcement and Crowd Control
Mounted police units operate in cities around the world, and their value comes down to physics and psychology. A mounted officer sits roughly 10 feet above the ground, providing an elevated vantage point that makes it far easier to monitor large crowds than patrolling on foot or in a vehicle. Horses can also navigate terrain that cars cannot, making them useful for patrols in parks, beaches, and urban areas with restricted vehicle access.
In crowd control situations, the sheer size of a horse creates a natural barrier that can redirect foot traffic without physical force. Mounted units also serve a community engagement role. People who might avoid interacting with officers on foot will often approach a horse, creating opportunities for conversation in neighborhoods where trust in police is low.
Agriculture and Forestry
In many parts of the world, horses still pull plows, haul loads, and work fields alongside their owners. Mongolia has 3.4 million horses for a human population of 3.3 million, and the animals remain central to herding, transportation, and daily survival on the steppe. In parts of Eastern Europe, Central Asia, and South America, working horses are the backbone of small-scale farming.
In forestry, draft horses have found a renewed role in environmentally sensitive logging operations. Heavy machinery creates networks of trails that compact and erode soil, destroying the topsoil layer and reducing fertility. In fragile forest ecosystems, this damage can be severe and long-lasting. Research comparing horse-assisted logging to fully mechanized operations found that a mixed animal-and-machine system produced nearly 45% lower greenhouse gas emissions per hectare than machinery alone. Horses harvest timber more slowly, but they leave the forest floor largely intact, making them the preferred option in protected areas and on steep, delicate terrain where soil preservation matters more than speed.
Ceremonial and Military Roles
Horses no longer charge into battle, but they remain a fixture of military ceremony. At Arlington National Cemetery, the Caisson Platoon of the 3rd U.S. Infantry Regiment has provided horse-drawn funeral services since 1948, using a traditional six-horse hitch configuration with three riders. The Army recently invested $5 million in herd management for the program and lowered the average horse age to 8 to 10 years, selecting animals for specific sizing, temperament, and discipline requirements. Eligibility for caisson funerals includes service members killed in action, Medal of Honor recipients, and senior officers.
Similar ceremonial roles exist worldwide. The British Household Cavalry escorts the monarch during state occasions. Royal guards on horseback serve in countries from Spain to Morocco to Thailand. These roles are symbolic, but the standards for the horses are exacting, requiring animals that remain calm amid cannon fire, marching bands, and dense crowds.
Pharmaceutical Production
Horses play a little-known role in pharmaceutical manufacturing. The drug Premarin, one of the most widely prescribed hormone replacement therapies for menopausal women, is derived from the urine of pregnant mares. The name itself comes from “pregnant mare urine.” Originally developed by a Canadian firm, the drug contains a complex of estrogens that cannot be synthesized identically in a lab. The industry has been controversial for decades, raising animal welfare concerns about the conditions in which mares are kept during collection. While the market for Premarin has shrunk as synthetic alternatives have become available, horse-derived estrogens remain in clinical use.
Horses are also used to produce antivenom and certain antibody-based treatments. Because of their large blood volume, horses can be immunized against snake venom or bacterial toxins and then have their blood drawn to extract the resulting antibodies at scale.
Recreation and Companionship
The largest single category of horse ownership in many countries is recreational riding. Trail riding, casual lessons, and pleasure riding account for millions of horses in the U.S. and across the European Union, which supports a herd of about 7 million equines and 800,000 jobs in breeding, sport, and tourism. Equine tourism is a growing segment in countries like Iceland, Ireland, and Argentina, where guided horseback trips draw visitors specifically for the riding experience.
For many owners, horses are simply companions. The bond between horse and rider involves daily care, training, and trust-building that resembles the relationship people have with dogs, just on a much larger and more physically demanding scale. The USDA’s 2022 Census counted 2.41 million horses and ponies across more than 63,000 farms in the United States, and a significant share of those animals are kept primarily for personal enjoyment rather than commercial purposes.
Search and Rescue
Horses are used in search and rescue operations in wilderness areas where vehicles cannot go and where covering ground on foot would take too long. A rider on horseback can scan a wider area than someone walking, move faster over rough terrain, and carry supplies or an injured person out of remote locations. Mounted search teams operate in national parks, mountainous regions, and rural areas across North America and Europe, often staffed by volunteer riders with specialized training.
