According to Census 2000,

281.4 million people were

counted in the United States —

143.4 million of whom were

female and 138.1 million male.1

The former made up 50.9 percent of the population, compared with 51.3 percent in

1990.

Information on gender was

derived from a question which

was asked of all people (see Figure 1). A

question on the sex of individuals was

included in all censuses since the first one

in 1790. 

This report, part of a series that analyzes

population and housing data collected by

Census 2000, presents the number who

are male and female in regions, states,

counties, and places of 100,000 or more

and highlights comparisons with data

from the 1990 census.2

The male population continued to

grow slightly faster than the

female population.

Between 1990 and 2000, the male population grew slightly faster (13.9 percent)

than the female population (12.5 percent).

The excess of the female to male population dropped to 5.3 million in 2000, compared with 6.2 million in 1990. This

resulted in the male-female ratio (the

number who were male times 100 divided

by the number who were female) increasing from 95.1 in 1990 to 96.3 in 2000.

The decline in the male-female ratio until

1980 resulted mainly from the relatively

greater reduction in female mortality

rates. The male-female ratio reversed its

downward trend between 1980 and 1990

as male death rates declined faster than

female rates and as immigration brought

in more men.

Figure 2 shows how male-female ratios

fluctuated for every decade since 1900.

From 1900 to 1940, the male-female ratio

was above 100, but beginning in 1950, it

fell below. Between 1980 and 2000, the

male-female ratio gradually increased.

The male-female ratio declined

with age after age 24.

Up to age 24, the male-female ratios were

about 105, reflecting the fact that more

boys than girls are born every year and

that boys continue to outnumber girls

through early childhood and young adulthood. The male-female ratio dropped

gradually in the working age groups, from

105.1 in the age group 15 to 24 years to

United States, including the 50 states and the District of

Columbia. Data for the Commonwealth of Puerto Rico

are shown in Table 1 and Figure 4. 2 1990 populations shown in this report were originally published in 1990 census reports and do not

92.2 for the age group 55 to 64 

(see Figure 3).3 Among older

adults, the male-female ratio fell

rapidly, as women increasingly outnumbered men at older ages and by

the age group 85 and over, the

male-female ratio was 40.7.

Male-female ratios increased

from 1990 to 2000.

Figure 3 also illustrates changes in

the sex composition by age

between 1990 and 2000. In 1990,

the number who were male about

equaled the number who were

female (a ratio of 99.9) in the age

group 25 to 34. In 2000, the malefemale ratio in the age group 25 to

34 increased to 101.8. The age at

which the number was almost equal

shifted closer to the age group 35

to 44 in 2000. The largest increases in the male-female ratios from

1990 to 2000 occurred in the age

group 55 and over. In 2000, the

ratio was 92.2 in the age group 55

to 64 compared with 89.4 in 1990.

In the age group 65 to 74, the ratio

was 82.3 in 2000 compared with

78.1 in 1990. The greatest increase

in the male-female ratio was in the

age group 75 to 84, where the ratio

increased from 59.9 in 1990 to

65.2 in 2000.

3 Note that comparisons of census counts

can be affected by differences in the completeness of census coverage between groups being

compared. For example, men are usually covered less completely in the census than women,

which would lower the male-female ratio calculated from census data. The male-female difference in net coverage tends to be greatest for

adults under age 65, particularly for Blacks or

African Americans.

The relative size of the male

and female populations varied

by geographic region.4

Table 1 shows that among regions

in 2000, the Northeast had the lowest male-female ratio — 93.5. The

Midwest and South had male-female

ratios in 2000 of 96.1 and 95.9,

respectively. The West had the

highest male-female ratio, at 99.6,

approaching parity between the

sexes. The regional male-female

ratios in 2000 follow the same pattern as in 1990.

At the state level in 2000, those

who were female were more numerous than those who were male in all

but seven states: Alaska led the

states with the highest male-female

ratio (107.0), followed by Nevada

(103.9), Colorado (101.4), Wyoming

(101.2), Hawaii (101.0), Idaho

(101.0), and Utah (100.4). All of

these states were in the West. In

contrast, the lowest male-female

ratios were recorded in Rhode

Island (92.5), Massachusetts (93.0),

and the District of Columbia (89.0).5

Over the decade, five states in

the West grew at a faster rate

than the other states, with the

male population growing

slightly faster than the female

population. 

Over the decade, the West experienced the fastest population growth

at 19.7 percent followed by the

South with 17.3 percent. In the

West, the male and female populations grew at about the same rate,

19.8 percent and 19.7 percent,

respectively. In the South, the male

population grew by 18.2 percent

and the female population by 

16.4 percent (see Table 1). 

In the five states with the highest

percent increase in total population

(Nevada, Arizona, Colorado, Utah,

and Idaho), the male population

grew faster than the female population between 1990 and 2000. In

the fastest growing state of Nevada,

the male population grew by 

66.4 percent and the female population by 66.1 percent. In the second fastest growing state of

Arizona, the male and female populations grew by 41.4 percent and

38.6 percent, respectively. Between

1990 and 2000, the male population grew faster than the female

population in 42 additional states.

There were only three states

(Alaska, California, and Hawaii)

where the female population grew

at a faster rate than the male population. In Alaska, the female population grew by 16 percent compared

with 12 percent for the male population. In California, the rate of

growth was 14 percent for the

female population and 13 percent

for the male population. In Hawaii,

the rate of growth for the female

and male populations were 11 percent and 8 percent, respectively. 

The only decline in total population

over the decade was in the District

of Columbia. The population in the

District of Columbia declined by 

6 percent with the male population

declining by 5 percent and the

female population by 7 percent. 

The female population

outnumbered the male

population in most counties 

in 2000. 

At the county level, the female population outnumbered the male population in most counties. Of the

3,141 counties and equivalent

areas, the number of counties with

a greater female population was

2,305 representing 73 percent of all

counties and equivalent areas.

About 42 percent or 1,315 counties

and equivalent areas had malefemale ratios below the U.S. malefemale ratio of 96.3.

The counties with low male-female

ratios were concentrated in the

Northeast and South. Most states

in these regions predominantly had

counties with low male-female

ratios, except for a few counties in

upstate New York and the Florida

panhandle. The female population

exceeded the male population in all

counties in Maine, New Hampshire,

Massachusetts, and Delaware. The

female population also exceeded

the male population in most counties in Vermont, Rhode Island, New

Jersey, Alabama, Mississippi, and

South Carolina.

In contrast, counties with high

male-female ratios were primarily in

the West. All counties in Nevada,

Alaska, and Hawaii had male-female

ratios above 100. Other states with

the majority of their counties with

high male-female ratios were Idaho,

Oregon, and Colorado.

Among the ten places of

100,000 or more with the

highest male-female ratios,

half were in California.

Seven of the places of 100,000 or

more with the highest male-female

ratios were in the West and three

were in the South (see Table 2).

Five of these places were in

California: Salinas, Santa Ana,

Sunnyvale, Costa Mesa, and

Oxnard. Salinas, California had the

highest male-female ratio (113.7),

followed by Fort Lauderdale, Florida

(110.0) and Paradise, Nevada

(109.1).6 Of the 245 places with a

population of 100,000 or more, the

male population exceeded the

female population in 44 places.7

Eight of the places of 100,000

or more with the lowest malefemale ratios were in the

South.

Eight of the places of 100,000 or

more with the lowest male-female

ratios were in the South. They were

New Orleans, Louisiana; Mobile,

Alabama; Baltimore, Maryland;

Shreveport, Louisiana; Pembroke

Pines, Florida; Richmond, Virginia;

Jackson, Mississippi; and

Birmingham, Alabama. One place

was in the Midwest (Gary, Indiana)

and one place was in the Northeast

(Philadelphia, Pennsylvania), as

shown in Table 3. Gary, Indiana

had the lowest male-female ratio

with 84.6, followed by Birmingham,

Alabama (85.7); Philadelphia,

Pennsylvania (86.8); and Jackson,

Mississippi (86.9).

The male-female ratios of the

ten most populous cities

varied.

Table 4 illustrates the male-female

ratio for the ten largest cities in

2000. Of the ten largest cities in

2000, the male population exceeded the female population in three

cities: Phoenix, San Diego, and

Dallas. The male and female populations were about equal in Los

Angeles and Houston. Philadelphia

and Detroit had the lowest malefemale ratios, at 86.8 and 89.1,

respectively.
