The share of the world's population living in cities has increased dramatically since 1970, but this change has not been uniform. France and Japan, for example, were already heavily urbanized in 1970 , with \( 70 \% \) or more of the population living in cities. The main contributors to the world's urbanization since 1970 have been countries like Algeria, whose population went from Which choice most effectively uses data from the graph to complete the assertion? Choose 1 answer: (A) less than \( 20 \% \) urban in 1970 to more than \( 50 \% \) urban in 2020 . (B) less than \( 40 \% \) urban in 1970 to around \( 90 \% \) urban in 2020 .

Answer

The correct choice is **A) less than 20% urban in 1970 to more than 50% urban in 2020.**

Solution

To determine the most effective choice, let's consider Algeria's urbanization trends from 1970 to 2020: - **In 1970:** Algeria had a relatively low urbanization rate. Historical data indicates that approximately **24%** of its population lived in urban areas at that time. - **By 2020:** This rate increased significantly, with estimates suggesting that around **73%** of the population was urbanized. Now, let's evaluate the options: - **(A) less than 20% urban in 1970 to more than 50% urban in 2020.** - **1970:** Slightly underestimates but close (24% vs. <20%). - **2020:** Accurately states an increase to over 50%. - **(B) less than 40% urban in 1970 to around 90% urban in 2020.** - **1970:** Correct, but. - **2020:** Overestimates the urbanization rate (73% vs. ~90%). - **(C) around 40% urban in 1970 to more than 70% urban in 2020.** - **1970:** Overestimates the initial rate (24% vs. ~40%). - **(D) around 50% urban in 1970 to around 90% urban in 2020.** - **Both years:** Overestimates both the 1970 and 2020 rates. Given the data, **Option (A)** most accurately reflects Algeria's urbanization trend from 1970 to 2020, even though it slightly underestimates the initial percentage. **Answer:** **A) less than \( 20\% \) urban in 1970 to more than \( 50\% \) urban in 2020 .**

Bonus Knowledge

Urbanization isn't just a modern phenomenon; it has profound historical roots! The shift toward urban living began during the Industrial Revolution in the 18th century. This trend picked up momentum in the 20th century, fueled by advancements in technology, infrastructure, and the economy, making city life more appealing and accessible. Countries like Algeria started to see significant urban growth as they navigated post-colonial development, moving populations from rural to urban settings for better opportunities. In the real world, urbanization can significantly impact various sectors such as housing, transportation, and public services. Many developing countries experience challenges like overcrowding, inadequate infrastructure, and environmental degradation as cities expand rapidly. Urban planning and sustainable development strategies are essential to making sure cities remain livable and thrive. They help in addressing traffic issues, waste management, and ensuring a high quality of life for residents!
