Union density

The union density or union membership rate conveys the number of trade union members who are employees as a percentage of the total number of employees in a given industry or country.{{Cite web|url=https://www.ilo.org/wcmsp5/groups/public/---ed_dialogue/---dialogue/documents/genericdocument/wcms_165194.pdf|title=Trade union density and collective bargaining coverage: International Statistical Inquiry 2008-09|last=|first=|date=2008|website=International Labour Organisation|page=2|archive-url=|archive-date=|access-date=17 October 2019}} This is normally lower than collective agreement coverage rate, which refers to all people whose terms of work are collectively negotiated. Trade unions bargain with employers to improve pay, conditions, and decision-making in workplaces; higher rates of union density within an industry or country will generally indicate higher levels of trade union bargaining power, lower rates of density will indicate less bargaining power.

Causes

The causes of higher or lower union membership are widely debated. Common causes are often identified as including the following:

whether a jurisdiction encourages sectoral collective bargaining (higher coverage) or enterprise bargaining (lower coverage)
whether collective agreements to create a closed shop or allow automatic enrollment in union membership are lawful
whether the government, for instance through a Ministry or Department of Labour, actively promotes collective agreement coverage with a power to impose terms if employers refuse to bargain with the workforce
whether a country enables collective agreements to be extended by government regulations to all workers when the coverage rate reaches a majority in a sector, or similar level
whether laws on collective bargaining and strikes are more or less favourable

In the United States in 2015 there were 14.8m union members, and 16.4m people covered by collective bargaining or union representation. Union membership was 7.4% in private sector, but 39% in the public sector. In the five largest states, California has 15.9% union membership, Texas 4.5%, Florida 6.8%, New York 24.7% (the highest in the country), and Illinois had 15.2%.See Bureau of Labor Statistics, ‘[http://www.bls.gov/news.release/pdf/union2.pdf Union Members – 2015]’ (28 January 2016)

In December 2021, 14.3% of the Australian workforce were union members; this was a decline of more than 5 percentage points since 2010 and nearly 10 percentage points since 2005.{{cite web |last1=Sakkal |first1=Paul |title='Mugged by reality': Unions urged to shift focus from federal Labor to state action |url=https://www.theage.com.au/politics/victoria/mugged-by-reality-unions-urged-to-shift-focus-from-federal-labor-to-state-action-20211130-p59dmt.html |website=The Age |date=December 2021 |publisher=Fairfax Media |access-date=2 December 2021}}

In France while the overall union density is 8%, in companies over 50 employees this level reaches 43%.

US Bureau of Labor in 2010 notes a difference of median income of 200 dollars between union-members (917), and non-union members (717) without indicating if higher salaries link to more unionisation, or the reverse or in mutuality.{{Cite web |title=The Difference Between a Union and a non-Union Workplace |url=https://www.linkedin.com/pulse/difference-between-union-non-union-workplace-mohamed-salah |access-date=2022-06-12 |website=www.linkedin.com |language=en}}
