SBRindex by Country, UV Response Index

2. (Reference) SBRindex Model Calculation Method

With global environmental changes, ultraviolet (UV) radiation is becoming increasingly intense. In this context, assessing how well individuals in each country are coping with UV exposure is highly meaningful. UV radiation can cause skin aging and skin cancer, making it a direct concern for public health. In this post, we will briefly examine each country’s UV response based on the UV index, per capita income, and per capita sunscreen expenditure. A higher UV response capability suggests that a country will be “younger” and “healthier” in the future.

We will calculate the “SBRindex” (Sunscreen Response Index) here, where a lower SBRindex indicates better UV response.

Sunscreen SBRindex by Country

This index appears to be the first of its kind in the world. Despite searching for similar data, I couldn’t find any that links individual expenditures on sunscreen to a country’s ability to respond to ultraviolet radiation. Any shortcomings of this model will be gradually improved over time.

(Reference) SBRindex Model Calculation Method

SBRindex = (①UV Index) / (②Sunblock expenditure per capita / ③per capita income) / 1,000

The “SunBlock Response index (SBRindex)” was hypothesized by the team at Happy & Technology Co., Ltd., and calculated using the following three indicators. While some estimated data are included, the figures may not be exact. However, it is believed to be a significant aid in understanding preparedness for changes in the global environment. Using sunblock purchases as a basis is meaningful as it reflects individual preparedness within the population. The data types used in this survey are as follows:

① UV Index: Shows how much a country is exposed to ultraviolet radiation.

② Sunblock expenditure per capita: Indicates how much people invest in sunblock. (2023, $)

③ Per capita income: Used to examine the economic conditions that affect the purchase and use of sunblock. (2023, $)

The index is designed to decrease as per capita income increases. Therefore, a lower SBRindex value signifies better UV response capability and indicates a favorable condition. The countries to which this model is applied are the top 50 countries ranked by per capita income. These 50 countries are assumed to have the conditions necessary for the formation of the sunblock market as they fall within the top 25% globally in terms of per capita income.
