The United States has 63 national parks, which are Congressionally-designated protected areas operated by the National Park Service, an agency of the Department of the Interior.[1] National parks are designated for their natural beauty, unique geological features, diverse ecosystems, and recreational opportunities. While legislatively all units of the National Park System are considered equal with the same mission, national parks are generally larger and more of a destination, and hunting and extractive activities are prohibited.[2] National monuments, on the other hand, are also frequently protected for their historical or archaeological significance. Eight national parks (including six in Alaska) are paired with a national preserve, areas with different levels of protection that are administered together but considered separate units and whose areas are not included in the figures below. The 423 units of the National Park System can be broadly referred to as national parks, but most have other formal designations.[3]

A bill creating the first national park, Yellowstone, was signed into law by President Ulysses S. Grant in 1872, followed by Mackinac National Park in 1875 (decommissioned in 1895), and then Rock Creek Park (later merged into National Capital Parks), Sequoia and Yosemite in 1890. The Organic Act of 1916 created the National Park Service "to conserve the scenery and the natural and historic objects and wildlife therein, and to provide for the enjoyment of the same in such manner and by such means as will leave them unimpaired for the enjoyment of future generations."[4] Many current national parks had been previously protected as national monuments by the president under the Antiquities Act or as other designations created by Congress before being redesignated by Congress; the newest national park is New River Gorge, previously a National River, and the most recent entirely new park is National Park of American Samoa. A few former national parks are no longer designated as such, or have been disbanded. Fourteen national parks are designated UNESCO World Heritage Sites (WHS),[5] and 21 national parks are named UNESCO Biosphere Reserves (BR),[6] with eight national parks in both programs.

Thirty states have national parks, as do the territories of American Samoa and the U.S. Virgin Islands. The state with the most national parks is California with nine, followed by Alaska with eight, Utah with five, and Colorado with four. The largest national park is Wrangell–St. Elias in Alaska: at over 8 million acres (32,375 km2), it is larger than each of the nine smallest states. The next three largest parks are also in Alaska. The smallest park is Gateway Arch National Park, Missouri, at 192.83 acres (0.7804 km2). The total area protected by national parks is approximately 52.2 million acres (211,000 km2), for an average of 829 thousand acres (3,350 km2) but a median of only 208 thousand acres (840 km2).[7]

The national parks set a visitation record in 2017, with more than 84 million visitors and set a further record in 2018 with a 0.1% increase.[8][9] Great Smoky Mountains National Park in North Carolina and Tennessee has been the most-visited park since 1944,[10] and had over 14 million visitors in 2021.[11] In contrast, only about 7,000 people visited the remote Gates of the Arctic National Park and Preserve in Alaska in 2021.

Most Dutch Colonial homes you find today are actually from the Colonial Revival period of the early 20th Century. Original Dutch Colonial homes feature flared roof eaves and creative wood and brickwork. They are much more ornamental than classic Colonial homes, though the Dutch Colonial Revival style tends to be more subdued than the original Dutch Colonial homes.

Dutch Colonial Revival houses feature:

• Broad gambrel roofs that are visually similar to barn-style roofs
• Open-floor plans
• Flared roof eaves
• Split doors

The large barn-style roofs are the most identifiable feature of a Dutch Colonial home and even became known as “Dutch roofs.”

Queen Anne homes were popularized in the later Victorian era, beginning around 1880. This style is the quintessential Victorian home for many, with ornate woodworking and decor inside and out.

Queen Anne homes have key regional differences across the country, but maintain these essentials:

• Textured walls with decorative shingles or half-timbering
• Large round or polygonal tower at the home’s corner
• Steeply pitched and asymmetrical roof
• Decorative spindles on porches and trim
• Decorative single-pane or stained glass windows

Queen Anne architecture is most common in homes, but can also be seen in schools, churches, and office buildings.

Mediterranean home styles are made of stucco, so they’re most common in warm climate states like Arizona and California. These homes grew in popularity in the 1920s and ‘30s after being featured as homes for the rich and famous on the silver screen.

Mediterranean-style homes include Spanish and Italian architectural elements. These key features make them easy to spot:

• Stucco walls painted white or brown
• Classic red tile roofs
• Arched doorways and windows
• Ornamentation including wrought iron, heavy doors, and decorative tiles

Mediterranean homes still carry the feelings of class and luxury they were built with over 100 years ago, with an added element of history and charm.

Second Empire homes were a modern Victorian-era style that started in France before spreading through the Northeastern and Midwestern United States. Second Empire architecture features similar ornate Victorian trends, though generally offers a simplified Victorian aesthetic.

These elements help identify a Second Empire home:

• Uniquely shaped Mansard Roof
• Decorative window framing and dormers
• Decorative rails or balustrades around terraces and staircases
• Iron roof crest and eaves with support brackets

Second Empire homes are also easy to identify since they’re the only Victorian-era style that often features a symmetrical, rectangular floor plan.

The Pueblo Revival was inspired by the indigenous Pueblo people’s architecture in the Southwestern US. Pueblo homes were made of adobe or stucco and designed to handle the extreme temperatures of the desert.

Architects in California began to explore the Pueblo style in the late 19th century and the Pueblo Revival style spread across New Mexico, Arizona, and Colorado.

The Pueblo Revival hit its peak in the 1930s in Santa Fe, and these Pueblo-style elements are still popular in the Southwest:

• Rounded corners and irregular shapes
• Earth tones that reflect the desert colors
• Stepped effects with higher floors becoming smaller
• Flat roofs with parapet trim
• Exposed roof beams extending past the walls

The Pueblo Revival style is also commonly called Adobe or Santa Fe style architecture.

Townhomes are common in cities and densely populated neighborhoods. Townhouses are tall and narrow homes designed to make the most out of vertical space without too much of a yard or garden area.

Homes are considered townhouses when they:

• Share one or two walls with adjacent homes
• Have their own entrances
• Are built with multiple floors to maximize vertical space
• Often share a similar style to their neighbors’ homes and may operate under an HOA

Townhouses can be built to mimic other architecture styles, like Italianate and Greek Revival, while maintaining the condensed, vertical floor plan.

A college endowment refers to all the money that an institution receives in donations. However, endowment funds are not ‘no-questions-asked’ cash boosts for the college. Instead, endowments are tightly controlled investments that are supposed to be grown so that the interest can be used to upgrade facilities, hire new staff, provide scholarships or aid the college or its students in some way.

Over the past three decades, the total market value of the 20 largest college endowments has grown nearly tenfold — from $30.6 billion to $302.1 billion. As the size of college endowments has increased, so too has the debate over their purpose, management and ethical obligations.

To get a better idea of how college endowments have changed over the last 30 years, DegreeQuery looked at the market value of the 20 largest U.S. college endowments from 1990 to 2020.

30 Years of U.S. college endowments

Based on the most recent NACUBO survey of 810 universities, the total market value of endowments in 2018 was $624.3 billion. 48.3% of that is held by just 20 colleges. But why the huge growth in market value over the past 30 years? It might be something to do with how much of the endowment the university chooses to spend on operations or the return rates of the endowment’s investment portfolio. Due to their often wealthy donor base and long-term investment horizons, the largest university endowments can invest in a diverse array of asset classes, and often grow faster than the economy as a whole.

From 1990 to 2020, the market value of the 20 largest college endowments grew at an average annual rate of 8.5% — faster than the 6.6% average annual growth rate for the Fortune 500 over the same period. The universities with the fastest growth over the past 30 years include the University of Michigan, Duke University and the University of Notre Dame. Meanwhile, the endowments with the slowest growth include Emory University, Rice University and Washington University in St. Louis.

1. U.S. college endowments in the 1990s

From 1990 to 1999, the market value of the 20 largest U.S. college endowments grew at an average annual rate of 12.5% — the fastest of the last three decades. As you can see from our graph, over this period, the University of Michigan endowment rose from the 20th largest to the 17th largest, and the University of Pennsylvania rose from the 16th largest to the 12th largest. Meanwhile, the Columbia University endowment fell from the sixth-largest to the 11th largest. Although the University of Texas System endowment had the slowest growth of the 20 largest endowments over this period, it remained the second-largest endowment overall.

2. U.S. college endowments in the 2000s

Endowment growth is closely connected with the overall health of the economy. As of 2018, just 4% of endowment assets were held as cash, the rest invested in equities, fixed income instruments and alternative investment vehicles. In the lead up to the 2008 financial crisis — university endowments had increasingly invested in high-risk, illiquid investments like private equity, real estate and hedge funds. As a result, endowments lost tens of billions of dollars in value, with some schools losing more than 25% of their total endowment value. From 2008 to 2009, the total value of the 20 largest endowments fell 3.4%. Yale posted the largest percentage decline, losing 28.6% of its market value. Other university endowments that posted big losses from the recession include Harvard, Duke and Stanford.

3. U.S. college endowments in the 2010s

Endowment growth rates rebounded in the wake of the Great Recession, although growth was still slow compared to the 1990s. From 2010 to 2018, the market value of the 20 largest endowments grew at an average annual rate of 7.6%. This is more than the 3.5% average annual growth rate for 2000 to 2009, yet less than the 12.5% rate for 1990 to 1999. During this period, the biggest winners were the University of Pennsylvania, rising from 11th to 7th largest, and the Texas A&M University System, which rose from 10th to 8th largest. Lackluster performance at some of the wealthiest schools has prompted some universities to make major changes to their endowment management. In 2017, for example, Harvard announced it would lay off roughly half of its 230-person staff in the wake of poor investment performance.

As you can see, university endowments were big business over the past 30 years. Nowadays, students, policymakers and the general public are increasingly involved in the conversation surrounding their management, mission and societal impact. For example, the 2017 Tax Cuts and Jobs Act, which imposed a 1.4% tax on the net investment income of the wealthiest endowments, recently sparked a wave of criticism from university administrators. Elsewhere on campus, protesting students demanded their universities divest from fossil fuel companies.

As the debate rages on and endowments continue to grow, these visualizations help us see how we got to this point.

Methodology

To get a better idea of how college endowments have changed over the last 30 years, DegreeQuery looked at the market value of the 20 largest U.S. college endowments from 1990 to 2018. Data on endowment asset value by university came from the National Association of College and University Business Officers (NACUBO) and is unadjusted for inflation. In years when certain universities did not participate in the NACUBO survey, we estimated the endowment value based on the compound annual growth rate for all available years. Estimated figures include the market value of the endowment assets for the Texas A&M University System for 1990, as well as the market value of the endowment assets for the University of California system for the years 1990 through 1992.

Modern Tudor homes are inspired by Medieval European Tudor homes and often have a charming cottage aesthetic. They’re popular on the East Coast and in parts of the Midwest.

Tudor homes are an easy style to identify. They feature:

• Steeply pitched gable roofs
• Exposed and decorative half-timbering with stucco exterior
• Mixed-material brick or stone walls
• Casement windows in groups or with diamond shapes

The Tudor Revival reached peak popularity in the 1920s and is still widely popular today.
