Ranch house styles are the most searched style in the US today and are common in cities and suburbs across the country. There are various ranch house styles, including California and split-level ranch homes. The main distinguishing features between these styles are living space and home layout.
Ranch style homes feature:
- Single-story floor plans with low-pitched roofs
- Rectangular, “U,” or “L” shaped open floor plans
- Patio or deck space connected to the home
- Often includes a finished basement or attached garage
Ranch homes are the most popular homes in 34 US states — particularly in the Midwest and on the East Coast.
Prairie-style homes were made famous by the architect Frank Lloyd Wright. These homes celebrate and complement the natural beauty of the Midwestern landscape with low and long shapes in the floor plan and building elements.
Prairie-style houses showcase:
- Long and low-to-the-ground builds
- Flat or shallow roofs with overhanging eaves
- Thin bricks or stucco exteriors to match the house shape
- Minimalist yet stylized ornamentation
Prairie houses inspired the flat planes and natural elements popular in Mid-century houses.
1. From this valley they say you are going, I will miss your bright eyes and sweet smile, For they say you are taking the sunshine, that brightens our pathways awhile. (CHORUS) Come and sit by my side if you love me, do not hasten to bid me a-dieu, but remember the Red River Valley, and the cowboy who loved you so true.
2. I’ve been thinking a long time, my darlin’, Of the sweet words you never would say, now, alas, all my fond hopes must vanish. For they say you are going away. Repeat Chorus: Come and sit by my side if you love me, do not hasten to bid me a-dieu, but remember the Red River Valley, and the cowboy who loved you so true.
3. Do you think of the valley you’re leaving? Oh, how lonely and sad it will be! Do you think of the kind hearts you’re breaking, and the pain you are causing to me? Repeat Chorus: Come and sit by my side if you love me, do not hasten to bid me a-dieu, but remember the Red River Valley, and the cowboy who loved you so true.
4. I have promised you, darlin’, that never, will a word from my lips cause you pain; And my life, it will be yours forever If you only will love me again. Repeat Chorus: Come and sit by my side if you love me, do not hasten to bid me a-dieu, but remember the Red River Valley, and the cowboy who loved you so true.

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.
American popular music has had a profound effect on music across the world. The country has seen the rise of popular styles that have had a significant influence on global culture, including ragtime, blues, jazz, swing, rock, bluegrass, country, R&B, doo wop, gospel, soul, funk, punk, disco, house, techno, salsa, grunge and hip hop. In addition, the American music industry is quite diverse, supporting a number of regional styles such as zydeco, klezmer and slack-key.
Distinctive styles of American popular music emerged early in the 19th century, and in the 20th century the American music industry developed a series of new forms of music, using elements of blues and other genres of American folk music. These popular styles included country, R&B, jazz and rock. The 1960s and 1970s saw a number of important changes in American popular music, including the development of a number of new styles, such as heavy metal, punk, soul, and hip hop. Though these styles were not in the sense of mainstream, they were commercially recorded and are thus examples of popular music as opposed to folk or classical music.

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.

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.
Contemporary homes resemble the modern homes of the mid-20th century with a renewed emphasis on sustainability. Current contemporary styles are rooted in minimalism, which you can see in these key features:
- Asymmetrical exterior
- Clean lines
- Open floor plan layout
- Geometry highlighted in its structure
- Sustainable building materials and features
Contemporary homes aim to find beauty in a simple and appealing design with ties to nature and more warmth than modern home styles offer.
Federal-style homes became popular after the American Revolution and were a refined upgrade to the popular Georgian house style. They have the same recurring shape and symmetry as other Colonial house styles, but their delicate ornamentation sets them apart.
Federal Colonial homes often feature:
- A layout built around a central hall
- An elliptical fanlight and two flanking lights (windows) around the door
- Paladin or tripartite windows
The elliptical fanlights and paladin windows are key distinguishing features from Georgian-style homes.
Mid-century Modern designs are nothing new and have influenced interior design, graphic art, and house styles. Mid-century Modern homes are designed to embrace minimalism and nature. They’re also often modeled to appeal to a futuristic or abstract concept.
Mid-century Modern homes can be identified by their:
- Flat planes and clean lines
- Monochromatic brickwork
- Asymmetrical home layouts
- Nature-inspired interior
- Interior level shifts between rooms
Mid-century architecture is still widely popular today, as are Mid-century Modern interior design and furniture trends.
Italianate architecture continues the trend of asymmetrical design, romanticism, and Medieval influence — this time borrowing features from Medieval Italy. Italianate style is common up and down the East Coast and peaked in popularity between 1850 and 1880.
Italianate architecture features:
- Belvederes for natural light and airflow
- Overhanging eaves with decorative support brackets
- Tall and narrow or pedimented windows with rounded crowns
- Cast iron detailing and decor
Pattern books were becoming a popular way for craftsmen to build homes in different styles. This flexibility meant Italianate features were accessible for a variety of homes including large estates and urban townhouses.
The Parthenon in Centennial Park, in Nashville, Tennessee, is a full-scale replica of the original Parthenon in Athens. It was designed by architect William Crawford Smith and built in 1897 as part of the Tennessee Centennial Exposition.
Today the Parthenon, which functions as an art museum, stands as the centerpiece of Centennial Park, a large public park just west of downtown Nashville. Alan LeQuire's 1990 re-creation of the Athena Parthenos statue in the naos (the east room of the main hall) is the focus of the Parthenon just as it was in ancient Greece. Since the building is complete and its decorations were polychromed (painted in colors) as close to the presumed original as possible, this replica of the original Parthenon in Athens serves as a monument to what is considered the pinnacle of classical architecture. The plaster replicas of the Parthenon Marbles found in the Treasury Room (the west room of the main hall) are direct casts of the original sculptures which adorned the pediments of the Athenian Parthenon, dating back to 438 BC. The surviving originals are housed in the British Museum in London and at the Acropolis Museum in Athens.
