The poll found that women in particular are affected by fears about crime, with 66 percent saying crime worries affect their lives, compared to 47 percent of men.

The effect of crime worries is broader than it is deep. Just under a third of Americans, 31 percent, say concerns about crime have "a big influence" on their lives; 26 percent report "a small" influence, for a combined total of 57 percent. The rest, 43 percent, say crime worries don't affect their lives all that much.

There are a few possible reasons why crime worries are up, even though crime rates are down. Previous ABCNEWS polling has found that assessments of the crime problem are based largely on media reports. Coverage of recent crimes, such as school and office shootings, may have heightened concern.

Lack of information may be another cause for concern: Just 29 percent in this national survey feel they know "a great deal" about ways to protect themselves and their families from crime. Another 42 percent, though, feel they know a "good amount" about crime prevention.

Experience

Whatever the crime rate, there is a good deal of personal or family experience with some crimes. Forty-five percent of Americans — nearly half the public — say they or an immediate family member have had a home broken into or burglarized. Three in 10 also report being victims of car thefts and credit card fraud.

Though fewer report experiences with muggings (17 percent) or sexual assaults (15 percent), these still represent millions of Americans. A crime of the modern age is less prevalent: Four percent report having had a child threatened or stalked via the internet.

Happened to you or family member:
Home broken into:	45%
Credit card stolen:	30
Car stolen:	30
Mugged:	17
Sexually assaulted:	15
Child threatened online:	4

Prevention

When it comes to crime prevention, simple steps are perceived as the most effective. Around six in 10 Americans feel it's "very effective" to exercise extra caution when alone at night, and to tell children not to talk to strangers. Nearly as many also feel that strong window and door locks are very effective in deterring crime.

Not surprisingly, these are the steps most often taken: Nine in 10 say they've told children not to talk with strangers, and about eight in 10 say they have strong locks and exercise extra caution at night.

Other steps are less likely to be perceived as effective, and are less likely to be used. A third of Americans see self-defense lessons as very effective against crime; a quarter think it's very effective to carry Mace or a whistle; and nearer to one-fifth think it's very effective to carry a gun, knife or other weapon.

It follows that these tactics are less likely to be carried out. A third of Americans say they've carried Mace, a whistle or similar protection; and a quarter say they've carried a weapon or had self-defense lessons.

Expense may be associated with some of these items. For example, more than four in 10 Americans think home burglar alarms are very effective, but nearer to a quarter have had them; cost might be a factor. By contrast, steps that are free or relatively inexpensive — exercising caution, warning children about strangers and having good locks — are much more widely practiced.

Practice and Perception:
	Have Done It	Think It's Effective
Carry weapon	24%	22%
Self-defense lessons	25	32
Home burglar alarm	27	43
Carry Mace or whistle	33	27
Car alarm	37	27
Watchdog	45	37
Tell children about Internet safety	59	47
Extra caution at night	78	59
Strong door/window locks	82	55
Tell children not to talk to strangers	90	62

Worried

Worries about crime seem to reflect broad and general anxiety rather than specific and acute fears. This could be another reason (beyond the expense) that more people haven't taken specific anti-crime measures such as installing alarms.

Just two in 10 Americans, or fewer, are worried a "great deal" about having their home broken into, being mugged, sexually assaulted or murdered, having a child threatened online, or having their car stolen. A quarter report a great deal of concern about having a credit card stolen; 36 percent express a great deal of worry about having a child abducted — a result that probably reflects the enormity of that crime more than its likelihood.

Worry a great deal about:
Having a child abducted	36%
Having credit card stolen	25
Having home broken into	20
Having child threatened/stalked online	20
Being mugged	15
Being sexually assaulted	15
Having car stolen	11
Being murdered	9

Men and Women

While women are more likely to say crime worries in general affect how they live, men and women don't differ much when it comes to concern about the specific crimes mentioned above.

But there are some differences in what they do. Women are more likely than men to use extra caution at night and to carry Mace or a whistle; men, on the other hand, are much more likely to have carried a gun, knife or other weapon.

Differences between the sexes:
	Men	Women
Carry a weapon	31%	18%
Carry Mace, whistle	28	38
Extra caution at night	69	85

Other Groups

Money can't buy you happiness, but it might buy a sense of security: People in higher-income families worry less about specific crimes, perhaps because they live in more secure areas and have more money to spend on crime protection.

For example, in $50,000-plus households, just 7 percent worry a great deal about being mugged; in under-$25,000 households this worry jumps to 25 percent. There's a 16-point gap between these groups in worry about having a child abducted; a 14-point gap in worries about sexual assault.

Also, 52 percent of those with higher incomes have a car alarm; this drops to 23 percent in the lowest income group. Those with higher incomes are also more likely to have a home burglar alarm, and somewhat more apt to have taken self-defense lessons.

How income affects worries:
	$25K	$50K	Gap
Worry a great deal about:
Having a child abducted	46%	28%	18%
Child threatened online	31	13	18
Being mugged	25	7	18
Being sexually assaulted	20	6	14
Having home broken into	26	13	13
Having a car stolen	15	6	9
Credit card theft	28	21	7
Being murdered	9	5	4
Have a car alarm	25	52	27
