Methodology
The U.S. Cities With the Best Work-Life Balance 2021 ranking reveals the U.S. and global
cities with the best social, cultural and structural systems in place in order to
provide their residents with the most well-rounded work-life balance, in terms not only
of work intensity, but also livability, well-being and rights. As the third yearly
iteration since 2019, and the second since the pandemic began, the study also takes into
account how the shift to remote-working and the impact of Covid-19 has changed and
continues to affect work-life balance in major U.S. and global cities around the world.
The study first examined 50 major U.S. cities known for attracting professionals and
families for their work opportunities and diverse lifestyle offerings. Then, to
understand how the U.S. performs worldwide, an international study was conducted after
reviewing hundreds of global metropolises with similar offerings as well as sufficient,
reliable, and relevant datasets. The result is a shortlist of 50 in-demand international
cities, including 17 from the U.S. and 23 worldwide. As the third iteration of a
continuous study, this index includes 10 more U.S. and global cities than in 2019.
This index is not designed to be a city livability index, nor is it intended to
highlight the best cities to work in. Instead, it is designed to be a guideline which
supports the fulfillment of residents’ lives by improving the aspects of life which help
relieve work-related stress and intensity.
Factors and Scoring
The study was divided into three categories - Work Intensity, Society and Institutions, City Livability - comprising the following 18 factors which contribute to work-life balance during and beyond the pandemic. The cities in both the Global and U.S. deep-dive were assessed according to these factors:
Work-Intensity: Remote Jobs (%), Overworked Population (%), Minimum Vacations Offered (Days), Vacations Taken (Days), Unemployment (Score), Multiple Jobholders (%), Paid Parental Leave (Days).
Society and Institutions: Covid Support (Score), Healthcare (Score), Access to Mental Healthcare (Score), Inclusivity & Tolerance (Score).
City Livability: Affordability (Score), Happiness, Culture & Leisure (Score), City Safety (Score), Outdoor Spaces (Score), Air Quality (Score), Wellness and Fitness (Score), Covid Impact (Score).
Each factor consists of one or more indicators which were scored and averaged. The equation for scoring is as follows:
z-Score =
x - mean(X)
Standard deviation(X)
in short
x - μ
σ
For columns where a low value is better, the score is inverted such that a high score is always better:
z-Score inverted = -1 *
x - mean(X)
Standard deviation(X)
in short -1 *
x - μ
σ
Data is normalized to a [50-100] scale, with 100 being the best score. Therefore, the higher the score, the better the city ranks for that factor in comparison to the other cities in the index. The formula used is min-max normalisation:
score = (100 - 50) *
x - min(X)
max(X) - min(X)
+ 50
The final score was determined by calculating the sum of the weighted average score of all of the indicators. Below you can find a detailed description of each factor within the study, and the source used.
WORK INTENSITY
Remote Jobs (%)
The quantity of jobs that are workable from home as a percentage of all jobs. Locations
with a greater share of teleworkable jobs (aka remote working) may provide residents
with the ability to comply with strict social distancing requirements while also
maintaining regular employment and income.
Data taken from the "How many jobs can be done at home?" (Dingle & Neiman, 2020) white
paper, which uses job classification survey data to identify jobs that can be performed
from home, and applies this to job statistics to estimate the share of all jobs these
jobs account for. U.S. cities employ data at a Metropolitan Statistical Area level,
while country-level data was taken for all other cities. Where data was unavailable,
values for some countries were modeled using GDP per capita and percentage of population
with university degrees.

international $), latest data; World Bank – Percentage of population age 15+ with
tertiary schooling. Completed Tertiary, latest data.
Overworked Population (%)
The percentage of full-time employees working more than 48 hours per working week. The
International Labour Organisation (ILO) recommends a workweek of 40-hours and considers
weekly work of over 48 hours "excessive".¹ The “Overworked Population” is considered to
be the percentage of full-time employees working more than 48 hours per working week.
For cities in the United States and in the European Union, average number of hours of
work was incorporated into the country-level data to approximate percentages on a
city-level. For all other cities, country-level data was used to evaluate the average
working hours per week.

Statistics – Current Employment Statistics survey (State & Metro Area), 2019; EUROSTAT -
Average number of usual weekly hours of work in main job by sex, age and NUTS 2 regions.
Minimum Vacations Offered (Days)
The minimum number of compensated vacation days an employee is legally entitled to after
at least one year of service. Data was taken at a national level for a full-time,
five-day workweek (excluding public holidays). In the U.S., under the Fair Labor
Standards Act, no such federal or state-level regulations exist that require employers
to pay employees for time not worked, including holidays.² Despite this, time off
agreements are often negotiated between employer and employee. Data for U.S. cities is
based on the average number of reported paid holiday days for a private industry
employee after their first year of service (10 days per annum).³

Working Conditions ; Thomson Reuters – Practical Law database; Various national labour
departments.
Vacations Taken (Days)
The average number of used paid vacation days offered to full-time employees in a single
year. City-level data was used where available.
For U.S. cities, data was calculated by subtracting the unused vacation days from the
average number of days offered. The percentage of unused vacation days in the U.S. was
sourced at a state-level. For non-U.S. cities, country-level data was taken on the
number of vacation days used.

Deprivation study, 2018/17; UBS – Prices and Earnings study, 2018.
Unemployment (Score)
The unemployment rate for the metropolitan area or region in the first quarter of 2021.
This factor is expressed as a score where the higher the score, the lower the
unemployment rate. For cities that have not published their unemployment rate, the rate
was estimated using the quarter-to-quarter trend of the country. In rare instances,
national figures were used. Unemployed persons are considered those of the labour force
who are jobless, looking for a job, and available for work.
Sources: Official statistical websites of each metropolitan area/region/country.
Multiple Jobholders (%)
The percentage of employed people holding more than one job at any one time. The holding
of more than one job at a time can be a sign of engaging in precarious work, and is
often used as a financial coping tactic for those in economically vulnerable positions,
including minorities. Multiple job-holding can also expose workers to longer hours,
lower wages, and compromise their labour protections. The ILO has voiced concern about
incidence of multiple job-holding, describing it as a possible “sign of persons engaged
in irregular low-productive work, with an overlap to working poverty and an inability to
earn sufficient income on the main job alone.”⁴
Unfortunately, detailed geographical data on the number of multiple-jobholders is
underreported and not regularly published. However the latest available data where
possible was compiled from official statistics and independent research. All U.S. and
Canadian data is at a state and province level, respectively, while other cities use
national data. Values for Hong Kong and Bangkok are modelled estimates using national
figures for the percentage of part-time workers as a proportion of the workforce.

Paid Parental Leave (Days)
The number of paid family leave days from work afforded to employees by law. The sum
comprises the legislated number of days for paid maternal, paternal and parental leave,
and reflects the number of days compensated, regardless of benefits provided or level of
compensation. At the federal level, the U.S. does not mandate paid leave for parents,
but some states have recently passed relevant legislation (these include the states of
California, New York, Hawaii, and the District of Columbia). National data is used,
except for U.S. cities, which use state-level data.

SOCIETY AND INSTITUTIONS
Covid Support (Score)
The degree of income support provided by governments to workers affected by the economic
effects of Covid-19. This factor is expressed as a score where the higher the score, the
greater the support. It takes into account government programmes to replace income lost
due to Covid, length of unemployment benefits, consumer confidence, household spending
and general wage levels; as well as overall spending by governments to dampen the impact
of Covid on the economy. In addition, the level of covid cases and deaths was taken into
account.

Healthcare (Score)
The measure of a city’s healthcare system based on access, quality and satisfaction.
Country-level data was obtained from the Universal Health Coverage (UHC) index for
access and quality indicators, while U.S. cities also incorporate state-level data from
the Health Access and Quality (HAQ) study. Additional data was taken from healthcare
access indexes developed by the World Health Organisation and the European Commission.
Satisfaction survey results were taken at a city level.

Access to Mental Healthcare (Score)
The accessibility and effectiveness of governments in implementing mental health
policies aimed to care for individuals with mental health illnesses. This factor uses
national data on governance, access to treatment, and the environment necessary for
treatment. This factor also incorporates suicide rates and city-level survey data on
healthcare quality.

Inclusivity & Tolerance (Score)
The degree to which a city supports gender and LGBT+ equality, inclusivity and tolerance through legislation and opportunity. The score combines the following ‘Gender Equality’ (degree of gender parity), as well as the ‘LGBT+’ (inclusiveness and tolerance) factors:
Gender Equality:
Gender equality scores were developed using data on the level of difference in
economic opportunity and participation, educational attainment, health, and political
empowerment between men and women. City-level data was used for U.S. cities, with
country-level data used for non-U.S. cities.

Index, 2020; Council on Foreign Relations – Women's Workplace Equality Index, 2020;
OECD – Social Institutions & Gender Index, 2019.
LGBT+
For LGBT+ scores, the comprehensiveness of equality and protection (an emphasis on work
rights) legislation, health access, as well as political representation for the LGBT+
community were examined. The percentage of the population that identifies as LGBT+ was
also included, as environments in which a higher number of citizens feel comfortable
openly identifying as a minority is also a potential indicator of a tolerant and
supportive community.

CITY LIVABILITY
Affordability (Score)
Monthly living costs as a proportion of the average household income, after tax. A
basket of estimated monthly costs includes: rent, basic utilities costs, groceries,
internet connection, leisure activities, clothes, and eating out. A higher score
indicates a higher level of remaining monthly income (if any) after accounting for
these deductions.
Sources: OECD – Employment Database, latest; Numbeo – Cost of Living Index, data as of
April, 2021.
Happiness, Culture & Leisure (Score)
The degree to which residents are able to enjoy their environment after office hours, measured through the average perceived level of happiness as well as the accessibility and variety of a city’s cultural and lifestyle offerings. The score combines both of the following ‘Happiness’ and ‘Culture & Leisure’ factors.
Happiness
Score includes the average perceived level of happiness at a city level. In the rare
absence of city-level data, national data was used. The score is calculated from
survey responses evaluating the perceived happiness with one’s own life, as well as
the degree of positive and negative effects a respondent experiences.
Sources: Sustainable Development Solutions Network – World Happiness Report, 2020;
Walethub – Happiest Cities, 2019.
Culture & Leisure
The vibrancy and variety of cultural and lifestyle offerings in a city. The score
combines cultural city rankings, the number of persons employed in the cultural and
creative industries, and the amount of leisure facilities and activities available, such
as the number of sports stadiums, restaurants, parks, shops, entertainment and nightlife
venues per capita. Cities with an exceptional number of activities received
supplementary points.
Note: all data collected for this factor reflects pre-pandemic conditions where cultural
and lifestyle offerings were available without restriction. This was designed to measure
the vibrancy of a city's offerings under normal circumstances, with the hope that the
existing cultural framework of a location will allow it to return to a similar level in
the future.

City Safety (Score)
The degree of safety provided by a city in more than a dozen key areas, including
environmental, social and infrastructural security. Indicators include statistics on
injuries and fatalities, damage caused at an economic level, public opinion data, and
data on the vulnerability of a location to particular hazards.

Green Spaces and Weather (Score)
The prevalence and accessibility of a city’s urban green infrastructure as a score,
including its proximity to residents and the percentage of land allocated to green
space. Data on weather and daylight conditions that could affect the use of public
outdoor spaces was also incorporated. This includes average temperatures, the annual
number of rainy days, annual sunshine hours, and cloudlessness.
Significant weighting is placed on the green spaces indicator, as the existence of
favourable weather alone is not a condition for a good score in this section. Data is
collected at a city level.

Air Quality (Score)
Annual median particulate matter (PM2.5/PM10) pollution for the year 2019, represented
as a score. Data from pre-pandemic conditions was used in order to assess a city’s air
quality under normal circumstances, with a view that pollution levels may return to
similar levels in the future should measures not be taken to reduce them.
Daily average data was taken across all days of a single year, with the median pollution
level representing the overall score. Data was taken at a city level.

Wellness and Fitness (Score)
The general state of a community’s physical fitness and health as represented by a
population’s average life expectancy, as well as levels of inactivity, obesity, and the
number of fitness studios and gyms per capita. National data was used for life
expectancy at birth, while U.S. cities use city-level data. Adult obesity rates and the
prevalence of physical inactivity were taken at a national level, with U.S. cities using
state level data. Data on the number of gyms per capita is taken at a city level.

COVID Impact (Score)
The degree of social and economic impact on account of a location’s Covid-19-related
response. This factor is expressed as a score where the higher the score, the lower the
impact. Three dimensions of the impact were taken into account: public health, economic
and social. The impact on public health is quantified through cases and deaths relative
to population; the impact on economy through year-on-year GDP growth in 2020 and 2021;
and the impact on society through the severity of limiting measures put in place to
contain the pandemic, as well as changes in mobility patterns as a measure of the effect
of these restrictions.
