1 Correction to: Social Indicators Research https://doi.org/10.1007/s11205-021-02727-2

In the original publication, the errors in publication that occurred due to typesetting are corrected with this correction article.

The upper limit (Eq. 2) in the numerator was incorrectly published as i = 1. It should read i = 10. The corrected equation is given below:

$$ \sum\limits_{i = 1}^{i = 10} {n_{i} {{\left( \frac{i}{10} \right)^{2} } \mathord{\left/ {\vphantom {{\left( \frac{i}{10} \right)^{2} } {\sum\limits_{i = 1}^{i = 10} {n_{i} } }}} \right. \kern-\nulldelimiterspace} {\sum\limits_{i = 1}^{i = 10} {n_{i} } }}} $$

The note to Table 1, should read as:

*Note: We have written ‘happy society’ and ‘unhappy society’. Our goal was to be understandable with a few words, however, as Veenhoven (1984) has explained, the term happiness should be used to describe the state of an individual person only, it does not apply to societies. Thus, a society cannot be said to be happy, at best, most of its members will consider themselves to be happy. Conversely, a society cannot be said to be unhappy, at worst, most of its members will consider themselves to be unhappy.

Tables 2 and 3 are placed closer to their citations in the original publication.

In Section 5.1, under heading Happiness, the word “Word” has been removed from “Word Pew Research Center” in the first sentence and it should read as:

We used the 2014 data on happiness from the Pew Research Center in which happiness is measured using the national values for answers to the Cantril ladder question asking respondents to value their lives today on a 0 to 10 scale, with the worst possible life as a 0 and the best possible life as a 10.

The original publication is also corrected.
