Current Bay Area Air Quality

Posted In: Environment | Health

Fires are once again raging in California and air quality in one of the most populated metropolitan areas in the country (the San Francisco Bay Area) is quite poor. This map show current air quality in the Bay Area. For more information see the EPA’s Air Quality website.

AQI colors

EPA has assigned a specific color to each AQI category to make it easier for people to understand quickly whether air pollution is reaching unhealthy levels in their communities. For example, the color orange means that conditions are "unhealthy for sensitive groups," while red means that conditions may be "unhealthy for everyone," and so on.

Air Quality Index
Levels of Health Concern
Good 0 to 50 Air quality is considered satisfactory, and air pollution poses little or no risk.
Moderate 51 to 100 Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution.
Unhealthy for Sensitive Groups 101 to 150 Members of sensitive groups may experience health effects. The general public is not likely to be affected.
Unhealthy 151 to 200 Everyone may begin to experience health effects; members of sensitive groups may experience more serious health effects.
Very Unhealthy 201 to 300 Health alert: everyone may experience more serious health effects.
Hazardous 301 to 500 Health warnings of emergency conditions. The entire population is more likely to be affected.

Most Stressed States

Posted In: Health

Long-term stress has been shown to be detrimental for your health. While it’s probably not possible to completely eliminate stress from people’s lives, there are many individual choices and decisions that can influence the amount of stress that people experience, including where they live, what job they have, their socio-economic conditions etc. . . One interesting bit of data analysis looks at an aggregate level to understand how stress differs from state to state depending on specific economic, demographic and other geographic factors.

This post shows a map of the most stressed states in the United States. The map is color coded from red (most stress) to blue (least stress) as a ranked list. Stress is divided into several categories including:

  • Work Stress is calculated from data on work hours, commute times, job security, unemployment rate, income growth and other metrics.
  • Money Stress is calculated from data on income, debt, credit scores, bankruptcy, housing affordability, poverty levels and other metrics.
  • Family Stress is calculated from data on divorce rates, single parents, childcare costs, parental leave policies and other metrics.
  • Health and Safety Stress is calculated from data on adult health, depression, mental health, health insurance, physical activity rate, crime rate, and other metrics.

Data and tools: The data comes from Wallethub’s analysis of data from a wide range of sources including the US Census, BLS, CDC etc.. Unfortunately the data used is a ranked list rather than a set of scores. The ranking doesn’t tell you if a state is 10% more stressful or 10 times more stressful, just that one is higher than the other.
