Consolidated city-county governments merge two layers of local government into one

Local governments coordinate across jurisdictions through regional councils and planning bodies

Many local governments are part of Councils of Governments or Metropolitan Planning Organizations—regional entities that coordinate transportation, land use, and other shared priorities across city and county boundaries. Federal law mandates their establishment in any metro area with a population over 50,000.

Some California cities outsource their public services entirely to the county

Southern California's "contract cities" incorporate as municipalities but pay Los Angeles County for police, fire, and other services rather than running their own departments—a cost-saving model common across the region.

Two doctrines of local governance determine how much power cities actually have

Under what is known as "Dillon's Rule," local governments can only exercise powers explicitly granted by the state. Under "home rule," cities have broader self-governing authority—but the balance between the two depends entirely on state law.

Sanctuary cities limit how local agencies help ICE—such as restricting detainers, jail transfers, or data sharing—while still enforcing criminal law, leaving immigration enforcement mostly to federal authorities.

Special districts are a form of local government focused on a single purpose

Unlike cities or counties, which provide a wide range of services, special districts are created to perform a single function, such as water, transit, or mosquito control. They are governed by appointed boards, have independent taxing authority, and now number nearly 40,000 across the US.

US school distrists have greatly consolidated since 1940

Consolidation significantly decreased the number of independent school districts from approximately 117,000 in 1940 to just over 13,000 today, mainly driven by efforts to boost efficiency and balance funding across communities.

Walt Disney World essentially ran its own local government for more than 50 years

Portland, Oregon, ran under a commission government for more than 100 years

From 1913 to 2024, Portland operated under a commission form of government, in which five elected commissioners each directly managed their own city bureaus—a structure that was largely abandoned elsewhere in the US by the mid-20th century.

Smart city systems can increase positive feelings toward local government

A 2018 study analyzed 50 global cities to determine whether smart city technologies enhance residents' quality of life. It found that these technologies can decrease the time spent interacting with healthcare and government by 45% to 65%, while also decreasing the disease burden by 8% to 15%.

Rivalry between the AFL and NFL led to a merger—and the creation of the Super Bowl

Competition between the American Football League and the National Football League led to a 1966 merger agreement, with the Super Bowl created as a championship game to determine league supremacy before the two leagues were fully integrated.

Federalism creates tension between national and state power by design

Federalism assigns authority so that neither the national government nor the states entirely dominate the other or the people they govern. By creating overlapping claims of power, the system makes negotiation, conflict, and compromise a permanent feature rather than a failure.

Explaining concentrate and how concentrate-derived juice differs from its source

Developed to reduce the volume of goods—thus lowering storage and shipping costs—the concentration process uses pressure and heat to remove water, pulp, and skin from fruits. Concentrates provide significant flavor, sugar, and calories to foods in small quantities, but do not retain most of the fiber, vitamins, and other nutrients from the source fruit.

Loudoun County, Virginia, is considered the world's densest data center hub

Nicknamed "Data Center Alley," some estimates indicate that the region's approximately 200 data centers will generate over $1B in taxes in 2026, which county officials say will help lower residential property tax bills. However, from 2020 to 2025, wholesale electricity costs have risen by as much as 267% in areas near data centers.

The brain consolidates memories during sleep

During sleep, the brain appears to process memories from the day and encode them into long-term storage. At the same time, the brain prunes old memories out of the brain that are no longer useful. Understanding this process also sheds light a various neurodegenerative diseases.

An integrated circuit combines major circuit components onto a single device

Before 1958, these components were fabricated separately before manual assembly, introducing human error, delays, and higher costs. The invention of the IC laid the foundation for automated manufacturing, miniaturization, and improvements to speed and energy efficiency.

Why can't we just turn the empty offices into apartments?

As both rent prices and mortgage rates rise across the US, many companies have simultaneously continued operating hybrid or remote workforces post-pandemic. A podcast episode dives into why city dwellers aren't all living in their prepandemic break rooms just yet.

Dual-class stock structures separate equity and decision-making authority

In the past few decades, dual-class stock structures have become an increasingly popular way for companies to raise capital in public markets without allocating traditional shareholder voting rights. Meta, Estée Lauder, and The New York Times are companies that are famously dual-class.

Explaining the Ethereum merge in simple terms

Ethereum slowly switched the way it adds blocks to the chain. In 2022, it completed its transition from a proof-of-work model to a proof-of-stake model. That event, called “The Merge,” happened when it combined two Ethereum blockchains operating under different systems. For an explanation of proof-of-work and proof-of-stake, and the significance of switching from one to the other, read this article.
