Study reveals the cumulative effects of income and age on human well-being globally

In a recent study published within the Scientific Reports Journal, researchers evaluated the consequences of age and income on human well-being.

Background

The connection between age, well-being, and income is poorly defined. It’s theorized that higher income will eventually reach a ceiling point at which well-being doesn’t improve with income.

Studies have revealed that income is positively related to subjective well-being (SWB). Although increased income advantages for SWB diminish progressively, the general impact of income stays positive.

In regards to the study

In the current study, researchers examined the consequences of income, age, and other variables on human well-being, using the Gallup World Poll (GWP) dataset.

Records were collected from greater than 2.4 million individuals from 168 countries/regions. The hedonic well-being approach, specializing in each day experienced feelings/moods, was leveraged to measure SWB.

The Gallup survey measured ten each day experienced feelings and moods – stress, anger, worry, sadness, pain, enjoyment, interest in something, smiling/laughing, and feeling respected or well-rested.

Respondents were asked to point in the event that they had experienced any of them during the day before today. These served because the explanatory variables of life evaluation.

Additionally they reported if there had been instances up to now 12 months once they couldn’t buy sufficient food or provide adequate shelter.

They were asked to point any health problems which prevented them from performing tasks that folks their age could typically do. The relationships amongst variables were interpreted using a directed acyclic graph (DAG).

Moreover, the researchers built a structural causal model (SCM) using 26 variables. The whole cumulative effects of age on life evaluation and the natural logarithm of individual income and the natural logarithm of individual income on life evaluation were estimated. 

Findings

The ultimate (GWP) dataset comprised 1.6 million records from 163 countries/regions for the 2009-22 period. The whole cumulative effects of age on life evaluation were, on average, -6.1 x 10-3. The negative value meant that higher age was negatively related to life evaluation.

The whole cumulative effects decreased when the age was > 70, possibly as a result of selection bias, because the variety of observations for this age group was relatively lower than for others.

Increased age resulted in a decrease in life evaluation following any pathway within the DAG. That’s, the next age aggravated most aspects influencing life evaluation.

The whole cumulative effects of individual income on life evaluation were, on average, 0.146, peaking at around 6.5, i.e., 665 USD/12 months. Increased income contributed probably the most to well-being as much as the poverty line.

Contributions of upper income to well-being decreased but were all the time positive. Increased income consistently elevated SWB, albeit the consequences progressively moderated with income.

The whole cumulative effects of age on individual income ranged between -3.33 x 10-3 and -9.58 x 10-3, averaging at -2.15 x 10-3. Increased age all the time causes a possible decline in income, with a more significant effect amongst older individuals.

The authors noted that absolutely the values of the consequences of age on life evaluation were far more significant in countries in Europe, Oceania, and North America than in other countries.

The hostile effects of age on life evaluation were minor in Europeans in comparison with Asians/Africans. Alternatively, the positive effects of increased income on life evaluation were maximized in Africa as a result of poverty. The results of age on income were like that on life evaluation.

Conclusions

The researchers observed that higher age reduced well-being, whereas increased income improved well-being. Although they used one among the biggest global datasets, improvements may very well be possible if more data were available.

For example, the causal relationship between income and age may very well be elaborately assessed if data on educational level and work experience, amongst others, were available.

Furthermore, although GWP covered an extended period, observations in each wave (of the survey) were randomly sampled as an alternative of surveying the identical subjects.

Overall, interventions for improving health in aging societies remain probably the most effective means to enhance/maintain human well-being. While the next age, per se, shouldn’t be detrimental to well-being, it may lead to physical/mental health issues that may deteriorate overall well-being.

Further, the effectiveness of the next income is profound when the initial income is low. Nonetheless, increased income always improved well-being because its effects were positive in most pathways within the DAG.
