Two pie charts show a comparison of the proportion of people with different degrees and professions who worked in an engineering company in 1980 and 2008

The charts illustrate the

number

of employees who worked in an engineering company with different types of higher education certificates in 1980 and 2008.

Overall

, as can be seen in the two pie charts the

number

of workers with

PHD

certificates in different fields has grown over the

last

28 years ago

while

this

proportion for

people

with

master

's degrees was the same as it was. On the one hand, in 1980,

people

with a

degree

in

master

of

science

and colleagues who had only bachelor's degrees in art and

science

had the biggest shares in

this

company, about 73% in total. In 2008, the proportion of

people

who had a university

degree

in

Master

of

Science

, 29%, was still the same as in 1980

while

the first

degree

in

science

and arts faced a dramatic decrease in 2008, 9% and 14% respectively.

On the other hand

,

people

in 1980 did not tend to have

PHD

certificates and individuals with a

degree

in

PHD

of

science

and art had the lowest portions in the company

as well as

people

with

Master

of Art degrees.

However

, in 2008, the

number

of employees with

PhD

in

science

experienced a drastic 17% rise from 13% up to 30%.

Also

, the

number

of

people

with an arts

phd

had tripled and reached 7% in 2008

in addition

to a minor increase in

people

with a

master

of arts, about 1%.
