Who is going to use more electricity in the home?

November 18, 2021

The eia article Use of electricity in houses to grow more quickly in developing economies by Courtney Sourmehi (11/5/2021) is a good example of the difference between totals and per capita.

Reference case, we project that residential buildings outside the Organization for Economic Cooperation and Development (OECD) will consume more electricity than all residential and commercial buildings combined in OECD countries by 2050. However, people in non-OECD countries will, on average, still consume less than half as much residential electricity as in OECD countries.

What is driving the increase use of electricity?

Population and household income are key drivers of residential electricity consumption. Over the next 30 years, we expect the populations in non-OECD countries to grow three times faster than the populations in OECD countries. As standards of living rise in non-OECD countries, as reflected in increases in household income, we also project increased demand for electricity to power new household electronic devices and appliances, such as air conditioners and electric cooking ranges. In OECD countries, electricity consumption will grow more slowly because of less population growth, gains in energy efficiency, and slower increases in household income.

Why are more women completing college than men?

November 11, 2021

The Pew article What’s behind the growing gap between men and women in college completion? by Kim Parker (11/8/2021) notes:

Men are more likely than women to point to factors that have more to do with personal choice. Roughly a third (34%) of men without a bachelor’s degree say a major reason they didn’t complete college is that they just didn’t want to. Only one-in-four women say the same. Non-college-educated men are also more likely than their female counterparts to say a major reason they don’t have a four-year degree is that they didn’t need more education for the job or career they wanted (26% of men say this vs. 20% of women).

Women (44%) are more likely than men (39%) to say not being able to afford college is a major reason they don’t have a bachelor’s degree. Men and women are about equally likely to say needing to work to help support their family was a major impediment.

Also worth noting:

The reasons people give for not completing college also differ across racial and ethnic groups. Among those without a bachelor’s degree, Hispanic adults (52%) are more likely than those who are White (39%) or Black (41%) to say a major reason they didn’t graduate from a four-year college is that they couldn’t afford it.

There is information about the questions and methodology.

Do you need a simple climate model app for the classroom?

November 8, 2021

UCAR (University Corporation for Atmospheric Research) has The Very Simple Climate Model page with a climate model where you set the emissions and then run the model until 2100. You get graphs of carbon emissions, CO2 concentration, and temperature. For example, the output in the graph here set emissions at about half the current level. Even then temperature goes up a degree F by 2100. The model can be run 1 year at a time with different emissions each year. There is a link to an activities page as well as some scenarios to explore.

What are the U.S. opinions on police funding?

November 1, 2021

The Pew article Growing share of Americans say they want more spending on police in their area by Kim Parker and Kiley Hurst (10/26/2021) compares police spending polls from June 2020 and Sept 2021. The overall summary is in the graph copied here. There are other charts including a breakdown by race, ethnicity, age, and political leaning. For example,

Among Democrats, Black (38%) and Hispanic (39%) adults are more likely than White adults (32%) to say spending on police in their area should be increased. There is no significant difference across these racial and ethnic groups in the share of adults who say spending should be decreased.

Within the GOP, White and Hispanic adults differ in their views on this question: 64% of White Republicans say police spending in their area should be increased, compared with 53% of Hispanic Republicans.

Pew included a methodology section for both polls.

Do we need to reform our political system?

October 25, 2021

According to the Pew article Citizens in Advanced Economies Want Significant Changes to Their Political Systems by Richard Wike, Janell Fetterolf, Channon Schumacher, and J.J. Moncus (10/21/2021) people seem to think we need to reform our pollical systems.

Across 17 advanced economies surveyed this spring by Pew Research Center, a median of 56% believe their political system needs major changes or needs to be completely reformed. Roughly two-thirds or more hold this view in Italy, Spain, the United States, South Korea, Greece, France, Belgium and Japan.

In the chart copied here, the U.S. is again near the top. In this case only Italy and Spain have a higher percentage saying they need change. There are over a dozen charts analyzing the issue of wanting political change in the article.

How much have cod catches in Eastern Canada changed?

October 21, 2021

Our World in Data has an extensive post on Fish and Overfishing by Hannah Ritchie and Max Roser (first published Oct 2021). Here is one excerpt from this article:

In the chart here we see five centuries of cod catch in Eastern Canada. These fishing records date back to the year 1500. We see that fish catch started to increase from around 1700 through to the mid-20th-century. It peaked in 1968, before a collapse in fish stocks led to a dramatic decline. In fact, fisheries were forced to close 24 years later, in the early 1990s. Since then, stocks have not been able to recover due to the reopening of fisheries and their overexploitation afterwards.

You can download the data for this chart and more than a dozen others in the post.

 

How divided is the U.S.?

October 18, 2021

The Pew report Diversity and Division in Advanced Economies by Laura Silver, Janell Fetterolf, and Aidan Connaughton (10/13/2021) has the U.S. is the top spot in a poll and not in a good way.  The chart copied here from Pew has the U.S. at the top for conflict between political parties and even the second highest response from the U.S. would be third in the most common response.

Notably, however, in most societies racial and ethnic divisions are not seen as the most salient cleavage. Rather, in the majority of places surveyed, more people identify conflicts between people who support different political parties than conflicts between people with different ethnic or racial backgrounds. Political divisions are also seen as greater than the other two dimensions tested: between those with different religions and between urban and rural residents. (For more on the actual composition of each public surveyed on each of these dimensions, see Appendix A.)

The report has over 20 charts and rich context to discuss the quantitative results.

How did COVID impact K-12 learning based in income?

October 11, 2021

The Pew article What we know about online learning and homework gap amid the pandemic by Katherine Schaeffer (10/1/2021) has this to say:

Parents with lower incomes whose children’s schools closed amid COVID-19 were more likely to say their children faced technology-related obstacles while learning from home. Nearly half of these parents (46%) said their child faced at least one of the three obstacles to learning asked about in the survey, compared with 31% of parents with midrange incomes and 18% of parents with higher incomes.

This technology divide isn’t new:

Even before the pandemic, Black teens and those living in lower-income households were more likely than other groups to report trouble completing homework assignments because they did not have reliable technology access. Nearly one-in-five teens ages 13 to 17 (17%) said they are often or sometimes unable to complete homework assignments because they do not have reliable access to a computer or internet connection, a 2018 Center survey of U.S. teens found.

There are four other charts in the article.

How much CO2 have we emitted in the last 30 years?

October 4, 2021

The Institute for European Environmental Policy had this post that I missed in 2020 but it is still good: More than half of all CO2 emissions since 1751 emitted in the last 30 years (4/29/2020).

Slightly over half of all cumulative global CO2 emissions have taken place since 1990, the year of the first IPCC Assessment Report. The report re-confirmed anthropogenic climate change in a way that could not be ignored and led to the creation of the UNFCCC.

As a project you can do something similar comparing China and the U.S. using the U.S. and China CO2 Emissions projects under Calculus Projects.
